>Description:
xulrunner-2.0 fails to work on i386.
>How-To-Repeat:
run firefox-4.0, visit somewhere other than about:blank,
note how it gets a SIGSEGV doing a
movdqa %xmm0,0xffffffd8(%ebp)
(where -40(%ebp) is not 16-byte aligned)
at nsUTF8ToUnicodeSSE2.cpp:80
>Fix:
update GCC to something that knows what it's doing with SSE2
