As murphy would dictate, something fishy is going on. In the last 12 hours or so (I had a long sleep), I've started getting apparent memory corruption - although it only seems visible to userland. The usual symptom is that gas gets blocks of memory clobbered with 0xd0d0d0d0 (yes, the same fill pattern used in phkmalloc). This is highly suspicious. I'll keep everybody informed once I've narrowed down when it started breaking. My test machines had one last cvs update/merge conflicts/compile/reboot before commit. I hope I didn't fat-finger merging the conflicts or something silly right before commit. I have only seen it happen occasionally on one SMP box, the others appear OK. I have not seen problems show up on UP at all.
