Blead Breaks CPAN: BRUMMETT/Devel-hdb-0.23.tar.gz #16583
Comments
From @eserteThis is a bug report for perl from slaven@rezic.de, On FreeBSD systems (10 .. 12) the test Test failure looks like this: Can't get breakpoint: Can't connect to 127.0.0.1:44242 (Connection refused)# Looks like your test exited with 61 just after 6. Looking with truss into the test process one can see that 49835: 2.000253424 0.000032407 setitimer(0,{ 0.000000, 300.000000 },{ 0.000000, 0.000000 }) = 0 (0x0) The backtrace: #0 0x00000000004c4f57 in Perl_hfree_next_entry () I found also a CPAN Testers report from a linux system with http://www.cpantesters.org/cpan/report/84842889 The problem seems also to happen with the latest devel version Flags: Site configuration information for perl 5.28.0: Configured by eserte at Wed Jun 6 23:52:33 CEST 2018.

However, on the same system used in my previous report, I installed Perl 5 blead (197e798) and, using cpanm, was able to install Devel-hdb-0.23 against blead. Devel-hdb-0.23_14 failed, but with errors more like those seen in http://www.cpantesters.org/cpan/report/fd936088-4dd0-11e8-9eb2-d15040e7b18e. So these errors are clearly intermittent. -- |

I see similar failures (after 1-200 runs) on both 5.26.0 and blead, Whether its a problem with perl or elsewhere, I don't yet know. -- |

Working with the module's author, I have narrowed the issue and found a Using valgrind, I can now reliably reproduce the problem. $ cat Foo.pm $ cat foo $ valgrind ./perl -Ilib -I. -d foo The general issue is in trying to set a breakpoint on a line in the main It looks like a more general fix will need to be in perl itself. -- |

See #119801. I fixed this, but it broke Enbugger. I couldn’t figure out a way to get Enbugger to work with my patch in place, so I reverted it in despair. -- Father Chrysostomos |
From @rockyI had noticed that Enbugger broke (SEGV's) around 5.26.2 and suspected this Maybe the solution is to change Enbugger? On Wed, Jun 20, 2018 at 7:44 PM, Father Chrysostomos via RT <

I was able to install Devel-hdb-0.25 against Perl 5 blead today (on FreeBSD 13). The module is doing well on CPANtesters. So this ticket is closable. |
