Attached is a scripted dump of gdb running pulseaudio through the crash.
The salient bits are:
Program received signal SIGILL, Illegal instruction.

In other words, this binary contains SSE2 instructions (PACKSSDW) and thus does
not work on my Pentium III-m equipped IBM ThinkPad T23... that processor
supports SSE but not SSE2.
