Register a pthread cleanup handler to guarantee that `spa_source::{priv, rmask}` are cleared even if the thread is cancelled while the loop is dispatching. This is necessary, otherwise `spa_source::priv` could point to the stack of the cancelled thread, which will lead to problems like this later: Program terminated with signal SIGSEGV, Segmentation fault. #0 0x00007f846b025be2 in detach_source (source=0x7f845f435f60) at ../spa/plugins/support/loop.c:144 144 e->data = NULL; [Current thread is 1 (LWP 5274)] (gdb) p e $1 = (struct spa_poll_event *) 0x7f845e297820 (gdb) bt #0 0x00007f846b025be2 in detach_source (source=0x7f845f435f60) at ../spa/plugins/support/loop.c:144 #1 0x00007f846b0276ad in free_source (s=0x7f845f435f60) at ../spa/plugins/support/loop.c:359 #2 0x00007f846b02a453 in loop_destroy_source (object=0x7f845f3af478, source=0x7f845f435f60) at ../spa/plugins/support/loop.c:786 #3 0x00007f846b02a886 in impl_clear (handle=0x7f845f3af478) at ../spa/plugins/support/loop.c:859 #4 0x00007f846b172f40 in unref_handle (handle=0x7f845f3af450) at ../src/pipewire/pipewire.c:211 #5 0x00007f846b173579 in pw_unload_spa_handle (handle=0x7f845f3af478) at ../src/pipewire/pipewire.c:346 #6 0x00007f846b15a761 in pw_loop_destroy (loop=0x7f845f434e30) at ../src/pipewire/loop.c:159 #7 0x00007f846b135d8e in pw_data_loop_destroy (loop=0x7f845f434cb0) at ../src/pipewire/data-loop.c:166 #8 0x00007f846b12c31c in pw_context_destroy (context=0x7f845f41c690) at ../src/pipewire/context.c:485 #9 0x00007f846b3ddf9e in jack_client_close (client=0x7f845f3c1030) at ../pipewire-jack/src/pipewire-jack.c:3481 ... |
