Re: [Denemo-devel] Denemo sometimes hangs (crashes) on quit

[Richard Shann]

Is this with some MIDI hardware attached? The back trace unfortunately
doesn't lead back to any particular place in the Denemo code, but there
are mentions of thread primitives, which shutting down the audio threads
might involve. Does it just hang or does it return to the gdb prompt?
I presume this is from the latest sources - meaning basically it's
version 2.0.0?
