| Subject: | Segfaults/aborts in t/fail.t |
On some of my smoker systems t/fail.t fails either with a segmentation fault or a SIGABRT. I don't see a pattern regarding perl versions or operating systems.
In a debugging perl it looks like this:
$
perl5.24.0d -Mblib t/fail.t
1..19
...
ok 10 - Right message
perl5.24.0d: sv.c:6438: Perl_sv_clear: Assertion `((svtype)((sv)->sv_flags & 0xff)) != (svtype)0xff' failed.
[3] 25448 abort (core dumped) perl5.24.0d -Mblib t/fail.t
And a backtrace:
Program terminated with signal SIGABRT, Aborted.
