With HP C V7.1-015 on OpenVMS Alpha V8.3, -Duseithreads, I get
Failed 4 tests out of 1080, 99.63% okay.
[-.lib.ExtUtils.t]cd.t
[-.lib.ExtUtils.t]eu_command.t
[-.lib.ExtUtils.t]xs.t
op/threads.t
Fixes are available for cd.t and xs.t; since these are test patches
only and will not affect what gets installed, is it kosher to just
patch them and not take on the risk of a full-scale integration?
eu_command.t does not fail when run by itself and I haven't figured
out what it's tripping over (possibly a temp file left by some other
test that gets cleaned up later).
op/threads.t also fails on 5.8.8 (not the version that shipped with
it, but the new version of the test fails when run on 5.8.8). The test
that fails is labeled:
[perl #45053] Memory corruption with heavy module loading in threads
and it may well be that our dynamic loading code is a bit lacking in
the thread safety department. The crash is below. If this is the
only thing holding up 5.8.9, I think we should document it as a known
problem and move on.
