I build quite everything in Gentoo with -fomit-frame-pointer, but I haven
had so many problems, sometimes a build process fails, and many ebuilds
filter that flag (wine's doesn't anyway), but I never saw a problem like
that of a build process correct and then an internal problem.

I have resolved my problems removing that flag, however I can't be sure for
Nguyen Tuan Anh with Mandrake 10 because I don't have one and I don't know
if the Mandrake's flags are similar to the one Acke Carlsson sent me from
Mandrake 9.2 (but I think so). In this case that binaries are built with
-fomit-frame-pointer and the teory of Rein Klazes is right, the problems
are in Mandrake Binaries and by-hand compiled versions with
-fomit-frame-pointer flag (like mine).
