Once burnt, twice shy :) I once submitted a bug to Subversion and later found that they published my bug report including my mail address on a publicly accessible site where every spambot would find it. Which, in turn, makes me reluctant to ever do a similar thing again, hehehe :)
But, feel free to submit the snippet, if you like.
TDragon:
I can't reproduce this with the snippet. What I mean is, if you can provide me with enough of the source file to reproduce the problem in assembly, I can either create a patch myself or submit a formal testcase to GCC Bugzilla myself.
thomas:
I've tried putting the full function with the accompanying DynamicLibrary class in a new project that just calls the function from main() and nothing else. Unluckily, no optimizing crash in that case. Sending you the complete project that produces the bug is not possible, sadly.

Hi
i have just downloaded TDM-GCC 4.5.0 and successfully compiled the apache xerces but i cant run any example programs it gives a error
" The application failed to initialize properly (0xc0000005). click ok to terminate the application ".
In the msys shell i received some massages like auto import enabled without --enable-auto-import specified.
please help me , i am a newbie and i have a little knowledge in gcc and mingw.
with regards.............

hmm 0xc0000005 = access violation error. seems the code produced tries to write to an area in memory which is protected.
this is also one of the buggers im hunting a bit on mingw's java parts. the weird thing is its totally random but even when the affected executables dont show this the thing will still crash.
one of the main culprits i found where when using crossbuilt libraries (especially if built on linux for win32) one being libgnurx, i rebuilt it on windows and the problem went away.
the auto import thingy is just ld telling you that it uses auto import to satisfy all dependencies (dont worry about that) warning != will not run.
as for the access violation error i cant help much there im afraid would have to try the same code you used and see if it crashes here also.
