There has been one bug found in the garbage collector since 5.04.1,
which might have caused this.  Presumably if you ran the same program
under the same conditions it would fail in the same way (how long does
it take to fail?).  Is there any chance you could compile up the latest
CVS sources from the 5.04 branch and see if using that compiler helps?
