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 :)

Err.. Umm.. Tim,

Want to take another crack at it??? FTBFS:

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 reference with the patch I posted. It is possible that gcc was inlining 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. ;-)

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.

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??

Here is the backtrace:

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?
