I am unable to reproduce on my own machine. Can you figure out what object is segfaulting? is m_pEngineSync null? I suspect this is an initialization race condition that likely only affects this test because it uses an unusual code path.

I actually don't know. I just happened again, but looking at the coredump I doesn't look like m_pEngineSync is null:

`coredumpctl -1 gdb` has proven to be very helpful.

I think this is because I'm doing slotLoadTrack instead of loadTrack, which waits for the track to actually load. The test is quitting before the caching reader has a chance to finish

Ah, the loadTrack function waits for "istrackloaded", which returns true because the *old* track was already loaded. It doesn't actually wait to see if the *new* track is loaded. This is just a problem with signalpathtest.h. I'll fix.
