[Resent to daily-build, as nobody's responded on p5p]
I'm trying to nail this smoke failure:
[stdio/perlio] -Duseithreads
[perlio] -DDEBUGGING -Duseithreads
Inconsistent test results (between TEST and harness):
../ext/Hash/Util/FieldHash/t/02_function.tFAILED--expected 64
tests, saw 55
Whatever it is, it's a crashing bug -- see the log entry at the end
of the mail. My problem is that I can't reproduce it outside smoke.
I've tried running the offending test from at to kind of simulate
being run from cron and with various combinations of minimal
environment, closed or /dev/null-attached stdin, but the thing passes
every time both with TEST and harness:

Does anybody know what else I can try to make the damned thing fall
over?
