This is a bug report for perl from slaven@rezic.de, generated with the help of perlbug 1.41 running under perl 5.27.8. ----------------------------------------------------------------- Two tests in the Unix-Passwd-File-0.250 test suite fail with perl 5.27.8: ... t/get_group.t ............... Use of "goto" to jump into a construct is deprecated at /home/eserte/.cpan/build/2018020121/Unix-Passwd-File-0.250-0/blib/lib/Unix/Passwd/File.pm line 379. t/get_group.t ............... No subtests run ... t/get_user.t ................ Use of "goto" to jump into a construct is deprecated at /home/eserte/.cpan/build/2018020121/Unix-Passwd-File-0.250-0/blib/lib/Unix/Passwd/File.pm line 323. t/get_user.t ................ No subtests run ... Test Summary Report ------------------- t/get_group.t (Wstat: 11 Tests: 0 Failed: 0) Non-zero wait status: 11 Parse errors: No plan found in TAP output t/get_user.t (Wstat: 11 Tests: 0 Failed: 0) Non-zero wait status: 11 Parse errors: No plan found in TAP output So we have segmentation faults here (status=11). The test suite also failed with 5.27.7, but this was probably because of other reasons (smartmatch). Again no bisect; good start/end commits for a bisect may be found here: http://fast-matrix.cpantesters.org/?dist=Unix-Passwd-File-0.250;os=linux;perl=5.27.8;reports=1#sl=6,1 ----------------------------------------------------------------- --- Flags: category=core severity=low --- Site configuration information for perl 5.27.8: Configured by eserte at Sat Jan 20 09:22:10 CET 2018.

The error message appears in this recent commit: ##### commit dc6e8de0c8eef348cabc76d23a98ce74e4b90cde Author: Abigail <abigail@abigail.be> Date: Mon Jan 16 11:44:30 2017 +0100 There's an objection to fatalizing jumping into a construct. This reverts commit 84b32f52b10f9912b40ef378cd0b01f4aff80630. This reverts commit d30393aaade31b605724846a30a10dd1e96cd181. We need more debate on this one; either we should undeprecate it, or settle on an end-of-life version. ##### -- James E Keenan (jkeenan@cpan.org)
