Closed GerHobbelt closed 5 years ago

GerHobbelt commented 5 years ago

HTR:

Stacktrace is about 9200 lines when the lock instrumentation fails (lock took 115ms to release), showing a runaway stack: note the Qiqqa TxtBibTeX_TextChanged -> MoveDelta -> ReflectPDFDocument runaway in the trace below. (only part of the stacktrace; look for the 'at Qiqqa.' lines in here:
