I tried to reproduce, but my bluetooth setup is currently totally broken (bluetoothd isn't running), so there are no adapters to free, and the bug appears to be related to adapter freeing. I triggered another valgrind error when unloading module-bluetooth-discover, though: ==8272== Invalid read of size 1 ==8272== at 0xFF88674: defer_cb (module.c:314) ==8272== by 0x10235C63: dispatch_defer (mainloop.c:682) ==8272== by 0x10236833: pa_mainloop_dispatch (mainloop.c:891) ==8272== by 0x10236A00: pa_mainloop_iterate (mainloop.c:931) ==8272== by 0x10236A59: pa_mainloop_run (mainloop.c:946) ==8272== by 0x423F94: main (main.c:1136) ==8272== Address 0x10a3b9b8 is 72 bytes inside a block of size 88 free'd ==8272== at 0x4A07577: free (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==8272== by 0x102528C4: pa_xfree (xmalloc.c:131) ==8272== by 0xFF8811E: pa_module_free (module.c:240) ==8272== by 0xFF88382: pa_module_unload_by_index (module.c:267) ==8272== by 0xE8DDED7: module_bluetooth_discover_LTX_pa__done (module-bluetooth-discover.c:84) ==8272== by 0xFF8806C: pa_module_free (module.c:227) ==8272== by 0xFF88256: pa_module_unload (module.c:253) ==8272== by 0xFF88698: defer_cb (module.c:315) ==8272== by 0x10235C63: dispatch_defer (mainloop.c:682) ==8272== by 0x10236833: pa_mainloop_dispatch (mainloop.c:891) ==8272== by 0x10236A00: pa_mainloop_iterate (mainloop.c:931) ==8272== by 0x10236A59: pa_mainloop_run (mainloop.c:946) I found the bug in module.c, but fixing it properly will take some time. I hope I can get it fixed next week. It might fix the error you're seeing too, but probably not. -- Tanu _______________________________________________ pulseaudio-discuss mailing list pulseaudio-discuss@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
