I can provide the core dump if needed.

comment:3 by criezy, 3 years ago

Today I reproduced the crash while running the fullpipe german demo with valgrind. I am using up to date code from master (dd749854). I have attached the valgrind errors I get.

The crash is random, and when it does not occur none of these valgrind errors occur either. Thus I am suspecting a thread race issue (otherwise I don't really see why a variable would be initialise is some runs and not initialised in others).

I also suspect this might not be specific to fullpipe as a few weeks ago I got a crash starting drascula on iOS and the crash was also in mad_frame_decode().

ThreadSan finds the data race, so I am looking into this now.

Just in case anyone is curious about the reports:

SUMMARY: ThreadSanitizer: data race mp3.cpp:56 in Audio::BaseMP3Stream::endOfData() const

comment:7 by csnover, 2 years ago

After fixing the data race I now find the MP3 decoder usually doing an out-of-bounds read and crash:

  1. The _synth.pcm.length size is larger than the fixed-size buffers in mad_pcm so using that unchecked in BaseMP3Stream::fillBuffer causes an out-of-bounds read of the sample buffers.
  2. libmad itself is crashing at frame.c:453 with an out-of-bounds read because it does no bounds checking and has apparently a bad value for the header’s layer type that is out of range. Not sure yet if this is because the header has not been properly initialised or because it has been initialised with bad data.

Investigation is ongoing…

Owner: set to csnover
Resolution: fixed
Status: newclosed

Thanks for your report! A patch for this issue has been added in commit e42ade073cc1f013eae739dc37464630f1104813 and will be available in daily builds 1.10.0git-5480 and later.

If the audio thread happened to request data before a packet was ever added to the stream, it would cause the stream to never initialise the decoder’s structs and so they would contain uninitialised memory and crash.
