Hi,

Tried the -fwritable-strings. Doesn't solve the problem as the SIGSEGV 
occurs during the
loading of the executable and its DLL's.
I've tried the linker script that doesn't generate .rdata segments, both 
during the linking of the shared lib and the executable but that doesn't 
work in all cases and the application still crashes. It also happens when 
I'm trying to link against the static Xm library in combination with other 
shared libs that are dependend on it.

Puzzled...

Avi.
