Tim, Darrell, All:
I rebuilt TDE from 4/1 sources with full debug in attempt to further
look into
the kwrite crash that Darrell and I have experienced with TDE built on gcc
4.7.
With this build, if it is a source/bad patch/tde issue, then with my 3/29
build
giving no crash and my 4/1 build crashing, that would point to some
problem in
between those two dates. However, I am coming around to the thought that
-- this
isn't a TDE problem and is more likely a problem introduced by the gcc 4.7
interpretation of the TDE code. I will still have to build the 3/29
sources with
gcc 4.7 to confirm that to be the case. I have 3/29 binaries that work
fine
(which I'm fairly sure were built on gcc 4.7, but I can't remember). If I
rebuild with gcc47 on the 3/29 sources and get the same failure -- that,
in my
mind, conclusively points to the problem being gcc47.
If that is the case -- how in the heck do you debug something like that?
Upgrading gcc should NOT cause working code to start crashing unless the
C/C++ standard was violated somewhere. As ugly as it may be, we may need
to entertain the notion that gcc 4.7 is actually generating buggy code (it
would not be the first time, IIRC gcc 4.3 caused crashes as well that were
magically resolved with gcc 4.4).
That said, I hope you find something soon and that this is NOT a gcc
related issue!
Tim
