Summary0001765: Ardour2 crashes out when using punch-in record mode.
DescriptionDiscovered major flaw in write action, depth of bug was heightened by use of mtc. Recorded a passage then did punch in which first generated "disk too slow" errors. With MTC sync enabled playback continued where ardour would normally have stopped on error. Eventually this caused disk butler errors and crashes ardour with a segfault.

Maybe as a result ardour reporting jack zombie condition even though jack was running and functional. May or may not be related.

Note from Sampo:
the write_source is null
Additional Informationno space in Ardour-UI request buffer for thread disk butler

i have noticed a substantial increase in "p" buffer usage when slaving to mtc tho... increases the used amount by 20-30%.

track number is unimportant.crossfade "depth" is an issue here. if you have multiple crossfades present on the timeline at a given point and they are active (curves visible) this will cause playback to stop.
