I've been trying to update Test.pm but I'm getting bitten by intermittent
failures in I/O tests when I run "make spectest". These usually happen in
t/spec/S16-filehandles/io_in_for_loops.t and
t/spec/S16-filehandles/io_in_while_loops.t.
They *always* pass when I run:
make t/spec/S16-filehandles/io_in_for_loops.t
make t/spec/S16-filehandles/io_in_while_loops.t
I sometimes have to run "make spectest" several times before I can reproduce
this failure.
A typical failure result in the "make spectest" output stream looks like this:
Unable to open filehandle

These failures have been happening for at least a week (if memory serves
correctly) and may have existed before this, but I wasn't doing heavy testing
back then and thus don't know when this started.
