[Octave-bug-tracker] [bug #52996] calling audiodevinfo() results in a segfault on exit when JACK sound server is running

[Mike Miller]

Update of bug #52996 (project octave):

                  Status:            Works For Me => Confirmed

Follow-up Comment #6:

I can reproduce this crash now with the following


$ jackd -d dummy -p 512 &
$ octave-cli
>> audiodevinfo;
>> clear functions;


The crash occurs on "clear functions", when the audiodevinfo oct file is
unloaded, and recursively the portaudio and jack libraries are unloaded.

This crash only occurs for me when the jack server is started with "-p 512" or
a lower number. With the default "-p 1024" or a higher value the crash does
not occur.

Can you verify those findings?

Btw if you are using octave-cli, you can use gdb with just "gdb --args
octave-cli" with whatever options and arguments following that.

But I'm not able to get a very useful backtrace from gdb. I think this is
because the error is related to the jack library creating threads in the
background and then octave unloading the portaudio library while these threads
are still active.
