Python tracemalloc's "compare_to" function delivers always "StatisticDiff" objects with len(traceback)=1

Question

Using Python's 3.5 tracemalloc module as follows

tracemalloc.start(25)  # (I also tried PYTHONTRACEMALLOC=25)
snapshot_start = tracemalloc.take_snapshot()
...  # my code is running
snapshot_stop = tracemalloc.take_snapshot()
diff = snapshot_stop.compare_to(snapshot_start, 'lineno')
tracemalloc.stop()

leads in a list of StatisticDiff instances where each instance has a traceback with only 1 (the most recent) frame.

Any hints how to get there the full stack trace for each StatisticDiff instance?

Thank you! Michael

You need to use 'traceback' instead of 'lineno' when calling compare_to() to get more than one line.

BTW, I also answered a similar question here with a little more detail.
