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.
