I have found what was causing segfaults in Win32 builds during load (before
GDB was capable to do anything). I've got a working win32/qt4 mythfrontend
with this.
The explanation is rather complicated and will go to either TrollTech, or
GCC developers or to Microsoft when I will have time to analyze and put it
in words.
Regards,
Andrei Tanas.
