You need to find out what instruction it is dying on.  Rebuilding your kernel 
with CONFIG_DEBUG_USER might give you that information, otherwise you could 
use the debugger.  Once you know the faulting address, disassemble the region 
of code surrounding it and let us see the results.

It could be any of the above, though it seems unlikely a GCC problem would 
cause this.
