Bug#898075: jack: segfaults at start
Hello,
apparently the character string generated in jack_cursesmodule that is
passed to ncurses is invalid. I can't figure why this happen but I
suspect an issue in the python binding in jack_cursesmodule.
Hopefully you can bypass jack_cursesmodule to use the built-in ncurses
python binding.
It fixes the issue, and a patch is attached to this message.
I think it's a viable solution because according to the documentation
in the cursesmodule folder [1], the jack_cursesmodule is an old binding
of ncurses: version 1.5b1 from before the release of python 2.0 [2]
(see the version number at the beginning of jack_cursesmodule.c [3]).
So, using the official binding from python is a much more reliable
solution.
In addition, I can provide a non-maintainer upload for this package and
eventually maintain the package.
Best Regards,
François

Bug#898075: jack: segfaults at start
Package: jack Version: 3.1.1+cvs20050801-29.2+b1 Severity: grave Justification: renders package unusable Hello! I have just found out that jack stopped working in Debian testing. Last time I used it (around last December, on an up-to-date Debian testing box), it worked without any glitch. Now, when I try to encode one audio CD (*any* audio CD, including one that was successfully encoded in the past), I just get a segfault, immediately after selecting which FreeDB entry I want to use (when there is a multiple choice): $ jack -Q [...] Segmentation fault My /var/log/kern.log says: May 6 19:44:10 HOSTNAME kernel: [36919.353320] jack[10063]: segfault at 7f89 ip 7f89ed5665c1 sp 7ffee93b2398 error 4 in libc-2.27.so[7f89ed40d000+1b1000] My configuration file is: $ cat ~/.jack3rc # jackrc-version:31 ripper:cdparanoia base_dir:~/music/CDs unusable_chars:[' ', '/', ':', '?', '|', '>', '<'] replacement_chars:['_', '_', '_', '_', '_', '_', '_'] in case it makes any difference. Could you please try to reproduce the bug and fix it and/or forward my bug report upstream, as appropriate? Thanks for your time!
