hanspr has asked for the wisdom of the Perl Monks concerning the following question: Dear Monks, My apologies if I'm breaking a rule from your forum with this question. I've been helping a github project asbru-cm / gtk3 branch, written en perl and gtk3. We have a very strange and challenging bug to solve, I have already spent 2 weeks and I'm not getting any closer to solve it. I need some information on how to be able to debug this or guide me through the process, or If by any chance anyone has had a similar problem with the WINCH signal. You may find the transcripts of the bug on this thread The summary is this: The original code located at : pac_conn The code comes from example use in the module Expect
I have used strace on the process that gets killed and this is what I got, but I do not see how to use the information to get closer to the problem. strace: Process 1467 attached 21:01:07.691091 pselect6(1, [0], NULL, NULL, NULL, {[], 8}) = ?
