Package: portmidi
Severity: serious
Tags: patch upstream
Forwarded: http://sourceforge.net/apps/trac/portmedia/ticket/3
Hi,
Mixxx users encounter SIGSEGV with portmidi in ALSA-based Linux setup.
In order to reproduce the issue, you may try to plug a couple of MIDI
devices, say one of them is very chatty and you try to close it then
portmidi tries to poll the remaining open devices so you get a SIGSEGV
in handle_event().
The offending file is pm_linux/pmlinuxalsa.c, the upstream bug tracker
has already a patch attached and I'm going to prepare an NMU to fix this.
Hope to hear from you soon,
Cheers.
