Hi Andrew,
As mentioned over here, but probably lost in the noise of that thread:
... there is an intermittent crash in my new Parallel Hash code that
occurs only on your 32 bit Windows XP + Cygwin animal "brolga".
Unfortunately I haven't managed to come up with a theory to explain
this using only brain power and tea.
Would you mind trying to get a backtrace from that system? Either
from a regular make check failure, or perhaps it can be provoked by
running the attached script? I don't know anything about Cygwin
myself but I see that it's possible to get a core file that gdb can
load with "dumper":

Thanks,
