[Bug 38653] GCC 5.0,5.1,5.2 break -O2 optimization with 64-bit Wine

https://bugs.winehq.org/show_bug.cgi?id=38653

--- Comment #24 from Sebastian Lackner  ---
I don't know if this is already covered by the existing gcc bug reports, but I
noticed yesterday that even 32-bit wine compiled with gcc5.1 causes test
failures in d3dx9_36/mesh tests. It doesn't happen when Wine is compiled with
gcc4.9.

Could someone please check if this issue is still present after applying the
gcc fixes? In the worst case its another regression which has to be bisected.
