YUM seg fault on F12 on x86_64 with >4096M of memory

[Marcus D. Leech]

I'm having a really weird issue, and I'm sure that someone must have
heard of something like this.

Yum seg faults when I ask it to do "things" when I have >4096M of
physical memory installed.

I'm running on a system with a Core 2 Quad, QX9770, with a x86_64
install of Fedora 12 from
  LIVE CD.

If I drop physical memory down to <= 4096M, everything is happy.  But
for >= 4096M, not so happy.

Other parts of the system seem to be working OK. I can bring up Firefox,
muck about in it, etc.

My windows come up without issue.

But YUM can't seem to handle having too much physical memory (which just
strikes me as profoundly weird).

Any clues?
