Since you're compiling the VM yourself, you might want to add a guard that catches the condition and prints out the environmental values (oldLimit, delta, newSize, newDelta). I would suspect that this is a signed/unsigned issue with memory being allocated somewhere close to the 2GB barrier and then flipping from positive to negative. Since newSize and newDelta are declared int, this could easily happen.

Here is the result of: fprintf(stderr, "oldLimit=%p\ndelta=%d\nnewSize=%d\nnewDelta=%d\n"); oldLimit=0x80562b8 delta=-1077506096 newSize=0 newDelta=423027548 squeak: /tmp/squeak-svn/platforms/unix/vm/sqUnixMemory.c:175: uxGrowMemoryBy: Assertion `newDelta >= 0' failed.
