Description Joël Krähemann 2016-04-26 06:07:29 UTC

Advanced Gtk+ Sequencer is a realtime capable audio sequencer doing many threads to compute your audio tree. While doing playback involved with a lot of audio buffers copying, valgrind crashed.



Reproducible: Always

Steps to Reproduce:
1. compile and run gsequencer.org
2. simple setup with AgsPanel input linked to AgsFFPlayer output
3. open fluidsynth FluidR3_GM.sf2 in AgsFFPlayer and select Piccolo
4. add an editor index link it to AgsFFPlayer and try to play a quarter note

Actual Results:  
--5952-- VALGRIND INTERNAL ERROR: Valgrind received a signal 11 (SIGSEGV) - exiting
--5952-- si_code=128;  Faulting address: 0x0;  sp: 0x810f8ae20

valgrind: the 'impossible' happened:
   Killed by fatal signal

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what OS and version you are using.  Thanks.

Comment 4 Tom Hughes 2016-04-26 07:28:35 UTC

Were there any warnings from memcheck before valgrind crashed?

Although that crash appears as a valgrind internal error really it is most likely just a result of your malloc heap being corrupt given that it occurs in valgrind's malloc implementation.

So the first thing to do is to make sure that any issues valgrind has already reported before that are fixed.

Comment 5 Joël Krähemann 2016-04-26 09:40:26 UTC

Yes, there where many of them invalid read of size 2. This is probably since an mistake within a function causing buffer-overflow.

ags_recycling_create_audio_signal_with_frame_count() was affected but it is fixed for now in GSequencer. Valgrind doesn't crash anymore.

Thank you, you're doing a great job.
