Dolphin crashing on XP x64

I have a machine running the x64 edition of XP Professional, and I'm
having problems with Dolphin crashing on that machine. Sometimes when
doing "MemoryManager current compact" it crashes. It only happens after
I've ran some memory intensive tasks. I can perform similar actions on
my 32bit Vista laptop without any problems.

Has anyone else had problems with Dolphin on the 64 bit versions of
Windows? I've attached part of the crash dump below.
