[Mingw-users] Random linkage

[Manuel M. <mm...@ce...>]

Hello
I post this here hoping someone has a hint.

I updated to wxWidgets 2.9 some months ago and I also updated to new 
gcc's 4.5. It was hard because my PC couldn't cope compiling wx29. It 
stopped at some file with a severe error needed to be reported to gcc 
bug's tracker.
Each time I tried again, the file where it stopped was different.
This aspect and the fact that some other apps crashed made me think my 
PC had a RAM trouble, and I was true and replaced the broken module.
I decided to re-install everything on my HD partition.
I managed to get wx290 compiled and continue my own app develop.

But now my app crashes where it never did. Compiling it for debug, it 
doesn't crash. So I think wx29 was not really well-compiled for release.

I update again all my mingw files (2010-06-30) and recompiled 
everything. No problems compiling wx, but same problem on my app.

I tested my RAM with Memtest86+. It shows no errors. Nothing else in my 
PC crashes or produce wrong results.

I stored wx's .o and .a files in a different dir and compiled again.
Comparing both compilations I got surprised because some files differs, 
not only in some bytes but also in final size. I didn't changed a char 
between both compilations!
Changes are mainly in .a files. Is the linker broken?

The command I use is:
mingw32-make -f makefile.gcc BUILD=release UNICODE=1 USE_OPENGL=1 
RUNTIME_LIBS=static CPPFLAGS="-O3 -march=pentium3"
where makefile.gcc is that from wx distro

I know this probably is due to bad RAM. But nothing apart from compiling 
shows this behaviour.

So I'm trying in this mail-list

TIA
