It's crashing in the profiler while iterating through a std::map. Could be you've uncovered a rampant pointer.

I can't reproduce this crash. Even when loading some really huge and evil MIDI files.

Does this only happen with a specific MIDI file? If so, please attach the MIDI file to this bug report as it might help me to reproduce the problem.

Closing as it's been two years and no one else has confirmed. Please re-open and provide more details if this is still an issue. Thanks.
