Summary0007627: Crash, Illegal instruction in pthread_rwlock_unlock()
DescriptionI have a particular project file which causes Ardour to crash with "illegal instruction" or "illegal opcode" when I try to split a particular audio region. It's a large(ish?) project with a video timeline.
Steps To ReproduceLoad specific project (includes waiting for harvid etc)

Click on audio region

Press 'S' to split region

Ardour crashes
Additional InformationAttached is the backtrace from gdb.

I notice that bug http://tracker.ardour.org/view.php?id=6753 seems to have had a similar issue with with glibc's interpretation of how things should work :-/

I'll try and be available on IRC (agittins).
TagsNo tags attached.
