This seems to work. Without PIPE_ALIGN_STACK, fxarea has an 8-byte aligned
address, but with PIPE_ALIGN_STACK it is 16-byte aligned and the SEGV goes
away.
If preparing a final patch, remember that I had to add -mfxsr to CFLAGS to get
the patch using __builtin_ia32_fxsave to compile.
Thanks,
Chris.</pre>
