| Subject: | Segfaults, invalid pointers, abort() |
It seems that segfaults or similar things may happen while running the test suite. On CPAN Testers there are currently the following fail reports:
* http://www.cpantesters.org/cpan/report/fac5d046-6a2b-11e6-9e0c-49c858b9f28c
(perl 5.24.0 on a linux machine, perl is compiled with -DDEBUGGING)
* http://www.cpantesters.org/cpan/report/eff810bc-7380-1014-8411-edba5cf4dae8
(perl on a cygwin machine, signal 6 might be SIGABRT)
* not yet at CPAN Testers: perl 5.14.4 on a freebsd 9.2 machine, also compiled with -DDEBUGGING
A gdb backtrace looks like this:
Program received signal SIGSEGV, Segmentation fault.
