deadbeef uses few hacks in order to get rid of libstdc++ dependency in the static builds. specifically, it defines "int _Unwind_GetLanguageSpecificData;" and few other similar ones to shut up gcc error messages. from the backtrace (thread 13), it looks like jack plugin raises a signal (sigcancel), which triggers the __pthread_unwind in the adplug plugin, which in turn uses the functions that are explicitly defined as NULL in all c++ plugins in deadbeef. this is the cause of the crash.
it's not clear to me right now where to go from there. it doesn't look like correct behaviour from libjack side, in the first place, to do nasty things like that.
anyway, thanks for the heads up on the issue.
Original issue 1025 created by Alexey-Yakovenko on 2013-12-31T23:31:37.000Z:
What steps will reproduce the problem?
If I move all four plugins away from deadbeef's lib path than this error doesn't happen at all and I can play as many tracks as I want with the usual deadbeef rock-solidness.
I initially had deadbeef installed via pacman on Arch Linux from the official repositories some time ago. I never noticed any problems then (though I didn't use it that much). Today I installed from the Arch User Repository (AUR) both the jack output plugin and the MPRIS plugin:
https://aur.archlinux.org/packages/deadbeef-mpris-plugin/ https://aur.archlinux.org/packages/jack_output_for_deadbeef/
I think it was shortly after I had installed the MPRIS plugin that this first started happening. Therefore, I uninstalled both AUR packages and then also uninstalled deadbeef, rebooted my system, and reinstalled just deadbeef (all via pacman). However, the error continued to occur everytime.
I've now downloaded a copy of the source and have compiled and installed a development version in a seperate directory, and have replicated the fault there. I don't really know what's happening here. I have also updated Arch Linux today, so please let me know if this is being caused by something in my system rather than something in deadbeef. I googled "Unwind_GetLanguageSpecificData" and didn't find much.
I'm willing to do further debugging as necessary, though I can't promise I'll be very quick about it.
What is the expected output? What do you see instead?
Instead of playing the track, the application segfaults and this is printed to the console (the listed plugin depends on which of the four above I've still got enabled):
Segmentation Fault backtrace() returned 3 addresses deadbeef() [0x403940] /usr/lib/libc.so.6(+0x35390) [0x7f4beed6e390] /usr/lib/deadbeef/supereq.so(_Unwind_GetLanguageSpecificData+0) [0x7f4bdefa65a0]
What version of the product are you using? On what operating system and CPU architecture?

Please provide any additional information below.
FYI: My audio set-up is slightly fringe-case. Everything goes to ALSA which then goes to JACK via the ALSA-JACK plug-in, and JACK is running with FFADO to a firewire Presonus Firebox sound card. However, it's actually quite stable these days. Just thought I'd mention it.
