This is a bug report for perl from kentfredric@gmail.com,
generated with the help of perlbug 1.39 running under perl 5.18.0.


-----------------------------------------------------------------
[Please describe your issue here]

Under HARNESS_OPTIONS=j$N  with values of $N greater than 1, tests
randomly fail.

Some of them are pretty tragic, and result in errors resulting from
GCC not finding files:


t/002-more.t ............................. ok
===(     254;1   4/14   3/11 )==========================================
#   Failed test 'Line numbers created in output file, as intended'

<several hundred lines of omitted C source code printed to terminal>

# Looks like you failed 4 tests of 14.
t/001-basic.t ............................ Dubious, test returned 4
(wstat 1024, 0x400)
Failed 4/14 subtests
t/004-nolinenumbers.t .................... gcc: error: XSTest.c: No
such file or directory
gcc: fatal error: no input files
compilation terminated.

# Looks like your test exited with 2 just after 3.
t/004-nolinenumbers.t .................... Dubious, test returned 2
(wstat 512, 0x200)
Failed 8/11 subtests
