wine users - Apr 2011 - Detail level of backtrace depending on the used CFLAGS

Hello,

I've just noticed that I'm getting different backtraces depending on if
I use the -O2 or -O0 cflags during compilation.

Here is a backtrace with -O2: http://pastebin.com/bGXCJBND
And here is the one with -O0: http://pastebin.com/axPZQUaD

Both were produced by the same Wine version (wine-1.3.18-170-gfa2e4bb).

I'm using Fedora 14 32 bits and I always use the following CFLAGS when
compiling Wine:
"-g -gdwarf-2 -O2"

Which one is preferred e.g. when reporting bugs? What is causing this
difference?

Regards

The only time this can happen is when you get stack corruption with one and not
the other.
