in https://rt.cpan.org/Ticket/Display.html?id=37194#txn-641389 I reopened a bug concerning a Perl crash in conjunction with the libreadline XS bindings. I attached the necessary debug information, but until now there has been no acknowledgement from the maintainer. I want this finally fixed; it’s a major inconvenience to not have readline in Devel::REPL and the Perl debugger. My Perl guts and C夫 is nearly non-existent, so I can’t do the usual thing and produce a patch on my own. So I would like to employ your help; more eyeballs ↔ shallow bugs and all that.

My questions to you:

  1. Can you reproduce this crash despite -DPERL_USE_SAFE_PUTENV? If yes, let’s compare what is the common factor.
  2. Do you know what is the cause and how do you go about finding it?
  3. I have a debugging perl and know how to use gdb, but where do I have to set a breakpoint to observe the crash properly?

    The problem was that my perl never had safe putenv. The option is not -DPERL_USE_SAFE_PUTENV, but -Accflags="-DPERL_USE_SAFE_PUTENV".

    Doc patches to combat the mistake:
