backtrace

I can reproduce the problem on Fedora 19 32-bit, Wine 1.7.1 and GCC-4.8.1
installed.
This seems to be another bug related to gcc-4.8.x and the optimization levels
used when compiling Wine.
If I compile Wine with gcc-4.7.3 then the application doesn't crash.
Using gcc-4.8.1 the various optimization levels have different results:
-Og: no crash
-O0: no crash
-O1: crash
-O2: crash

In addition, native comctl32 works around the crash when using gcc-4.8.1.

Reverting the following commit in Wine 1.7.1 also works around the crash:
