Hmmm, my guess would be something related to libtool

Well, that's not 100% true. Disabling the MMX/SSE portion of the
build causes a fall back to the pure C code. The C code is completely
insensitive to the alignment of the allocated buffers - it's the
MMX/SSE code that insists on correct (16byte I believe) alignment.

But __slowly__ - the MMX/SSE optimizations will give somewhere
around a 4x (or more) increase in speed.

It does indeed sound encouraging - at least the coredump was avoided
but I wonder if that's because the MMX/SSE code was not built...
