in reply to return code 139

139 is the system return code to indicate a segmentation violation. I found a few references here and here
from the frivolous to the serious

    If the error returned is >128, subtract 128 to get the signal number. 139-128=11, SIGSEGV, segmentation violation.

    The following is from perldoc -f system:

    You can check all the failure possibilities by inspecting `$?' like this:

    $exit_value = $? >> 8; $signal_num = $? & 127; $dumped_core = $? & 128;

    -rr

[Corion]: Meh. I get the feeling I should post a call-to-action for people to test their modules with the upcoming 5.26 (or 5.25.latest), as it seems that the smoke testers don't really weed out modules that fail without . in @INC
[Corion]: But without instructions on how to easily test things yourself, I don't think such a call to arms is helpful
[Corion]: (this post on nntp.perl.org / p5p makes it seem to me that smoke testers seem to have a blind spot there)
[Corion]: Hmmm. Maybe setting $ENV{PERL5LIB}=" some path without dot"; perl Makefile.PL; make test already is enough to locally test your module...
[Corion]: Meh, no, will need a BEGIN hook...
[Corion]: ... and PERL5OPT does not like -e in it :-(
[Corion]: Ah. The magic invocation is set PERL5OPT=-M-lib=. (equivalent of no lib '.';
[Corion]: )
