Hi vm-dev,

>>> Good.  I'm off the hook :-)  Your subject line is misleading; this is a lock up, not a VM crash.  On Mac OS X I see the lock up but see no VM crash.  Does it help that you can start from the 6.0alpha download (6.0alpha) instead of starting from scratch?

Attached is a crash.dmp file.  This crash happened on the Win32 VM, squeak.cog.spur_win32x86_201803080952.  IIRC, I was trying to upgrade from #420 to #421.  The VM popped up a dialog box indicating some VM statistics and last opcode executed.  I failed to capture a screenshot.  I was never able to make the same situation crash the VM again after maybe 5 attempts — it only brought me an offer to enter the emergency evaluator.

Thanks,
Tim
