Hallo Ed, I think I can report something very similar:
I have not seen any "sort of crashes" but twice ProDeo 1.1 really crashed on my
computer in analysis mode. Both times it was just before finishing a 24 hour
analysis, so I expect it to be some sort of overflow, of the nodecounters maybe?
Windows terminates Pro Deo and asks to file a report. What I can see in
Dr.Watson's log that comes with Win XP is that both times there occurs a
division by zero. But what exactly gets divided is not clear to me.
This was the second position that was analyzed and crashed, from Michael
Drexel's post;

If there really is a way to mate in 14, Pro Deo 1.1 Vulcan does not see it yet.
I thought it was quite clever in finding a perpetual and securing a draw with
all those threatening pices in Black's corner. Bxh7+ in 6035 nodes, but not a
mate attack.
Nice position!

The raw stack dump was exactly the same the first time Pro Deo crashed, so I
suppose in principle the error should be reproducible? Maybe not a high priority
thing, but it may prevent analysing longer than 24 hours with Pro Deo if it
alway happens.
Goed weekend!
