    #24 0x080cc3d7 in x_wm_set_size_hint (f=0x0, flags=2,

Was f really 0 when this function was called?  (You can check by
looking at data in the calling function.)  If so, that was surely
incorrect, so please try to debug why the caller passed 0 for f.

It looks like this crash is in the middle of the X libraries,
and they were not compiled with debugging symbols.

If we are lucky, the f=0 will lead us to a bug in Emacs without the
need to poke around inside the X libraries.  But unless we have such
luck, it will be necessary to recompile using a debugging version of
those libraries.
