I'm seeing this on x86 FreeBSD with the JIT:
t/op/interp.........NOK 2# Failed test (t/op/interp.t at line 21)
Use of uninitialized value in concatenation (.) or string at lib/Test/Builder.pm
line 999.
# 'ok 1
# ok 2
# ok 3
# ok 3
# '
# doesn't match '/^ok\s1\n
# (?:PC=8.*)?\n
# ok\s2\n
# (?:PC=11.*)?\n
# (?:PC=13.*)?\n
# ok\s3\n$/x
# '
# Looks like you failed 1 tests of 2.
t/op/interp.........dubious
Test returned status 1 (wstat 256, 0x100)
DIED. FAILED test 2
Failed 1/2 tests, 50.00% okay
is this to be expected? It's now the only regression test that fails under
the JIT. Previously I think several were, but I can't remember for sure.
