Tim, Darrell, All,
tdelibs is the package that causes the kwrite/kate/etc.. crash when
built on
gcc 47. The backtrace is good this time and points to:
at (i=<optimized out>, this=<optimized out>) at
/opt/tqt3/include/ntqstring.h:641
641 { return i < d->len ? d->unicode[i] : TQChar::null; }
That is valuable information! This is also not an issue of ignoring build
warnings, as there are none which relate to the failing code.
If you can, please try the attached patch. It will probably do nothing,
but there is half a chance that gcc 4.7 did not inline the functions where
gcc 4.6 did, *potentially* causing a crash due to misuse of parameters
passed by reference.

I figured part of that was sour grapes from the OP, but I thought I would pass
it along in case there was a 'nugget' in there - couldn't tell either way.
I'm on the patch/rebuild and will report back :)

All of these crashes appear to be the result of a TQString passed by
reference from katerenderer.cpp that is disappearing before it is fully
processed.

Darn. I was running out the door when I wrote that;
I'll try to get
something better to you later.
All of these crashes appear to be the result of a TQString passed by
reference from katerenderer.cpp that is disappearing before it is fully
processed.
just a guess: could it be that that TQString is created and destroyed in a
different thread than that which uses it (and consequently crashes)?

It is possible, that is why I am allowing gcc to handle any passing by

the functions (and masking the potential crash) prior to gcc 4.7.
This is all just a shot in the dark until I can reproduce the bug here. ;-)

Ooh! Tim, kwrite really, really hates your patch! It opened OK, but the first

Darn. I was running out the door when I wrote that;
I'll try to get
something better to you later.
All of these crashes appear to be the result of a TQString passed by
reference from katerenderer.cpp that is disappearing before it is fully
processed.
just a guess: could it be that that TQString is created and destroyed in a
different thread than that which uses it (and consequently crashes)?

It is possible, that is why I am allowing gcc to handle any passing by

the functions (and masking the potential crash) prior to gcc 4.7.
This is all just a shot in the dark until I can reproduce the bug here.

Ooh! Tim, kwrite really, really hates your patch! It opened OK, but the
first
character I tried to type cause it to explode:
OK, this will have to wait until I can get a gcc 4.7 system up and running.

No kidding - Arch on virtualbox - about a 15-20 minute install. Really, really
simple, just create a new VM (it already has defaults for Archlinux, so if you
give your VM the name 'Arch x86_64' for example, it fills in the remainder of
the settings with Archlinux named as the distro.
Then just download the 'net install' either i686, x86_64, or 'dual' for
both and
boot your VM from it.
http://www.archlinux.org/download/
Then it is a simple matter of following the text prompt to type arch/setup,
accept the defaults and select both the 'base' and 'base-devel' sets of
packages
and your done -> you have the most current (based on official software releases
- not betas) distro going. Arch is rarely more than 3 days behind upstream. Get
lost, just ask or:

Tim, all,
Just drop a line back to the list when anyone has more information on this
issue. I am somewhat stuck building/debugging further on gcc 4.7 until we know
what we are dealing with here. I have had no other response/confirmations from
the suse folks on whether they have stumbled across this issue yet or not. I was
hoping to at least have a confirmation and be able to get more eyes on this
issue, but I doubt they have waded into the issue yet. If they have, they
haven't put it on the front-burner. I know Ilya has been test building on gcc47,
but I have heard anything back on whether they can reproduce it or not.
Since tdelibs is central to everything that happens in tde, it's hard to know
whether any new or existing issues seen are related/not related to whatever is
going on here. Can anybody think of any other tests I can run that might narrow
this down? Thanks.

Since tdelibs is central to everything that happens in tde, it's hard to know
whether any new or existing issues seen are related/not related to whatever is
going on here. Can anybody think of any other tests I can run that might narrow
this down? Thanks.

There was a new release of gcc 4.7.0-6 on Arch so I rebuilt everything
(tqt3->tdebase) and tried again. Same result :( However, the file not
found error looks strange. What gives with that error? - just do to
the random nature of this error or has a 't' 'q' bug been introduced??
OK, this will have to wait until I can get a gcc
4.7 system up and
running.

Tim, all,
Just drop a line back to the list when anyone has more
information on this issue. I am somewhat stuck building/debugging
further on gcc 4.7 until we know what we are dealing with here. I
have had no other response/confirmations from the suse folks on
whether they have stumbled across this issue yet or not. I was
hoping to at least have a confirmation and be able to get more eyes
on this issue, but I doubt they have waded into the issue yet. If
they have, they haven't put it on the front-burner. I know Ilya has
been test building on gcc47, but I have heard anything back on
whether they can reproduce it or not.

Ahh - learn something new every day :) Would it do any good to install the tqt3
source so it could find the file -- or is it just the infinite loop stray crash
where the source wouldn't help?

The backtrace still contains the same KateRenderer::textWidth()
function in it, so it's consistent with it being the same infinite
loop as before. Moreover gdb tells you the line number even if it can't
open the file, so you can look at the code yourself ;)
The "No such file or directory" error
is because gdb tries to open
the concerned file (kernel/qfont_x11.cpp, from TQt3 sources) to
show the line of code that program was executing.
