What is the faulting instruction?
movdqa, an SSE instruction that requires 16-byte alignment. This is
about a dozen instructions within the dynamic loader.
By some coincidence the same problem with movdqa cropped up (and a solution
found) in a perl forum:
http://www.perlmonks.org/?node_id=1052707
In a nutshell, the solution there was to invoke "__attribute__
((aligned(8)))", which meant that gcc generated movdqu instructions instead
of the faster movdqa.
I don't know if that necessarily helps here :-)
