Valgrind developers:
I ran into an issue with the valgrind callgrind tool running a python AI benchmark:
valgrind --tool=callgrind python3 bench_hnsw-short.py 1 hnsw_sq
==2282131== Callgrind, a call-graph generating cache profiler
==2282131== Copyright (C) 2002-2017, and GNU GPL'd, by Josef Weidendorfer et al.
==2282131== Using Valgrind-3.23.0.GIT and LibVEX; rerun with -h for copyright info
==2282131== Command: python3 bench_hnsw-short.py 1 hnsw_sq
==2282131==
==2282131== For interactive control, run 'callgrind_control -h'.
==2282131==
==2282131== Process terminating with default action of signal 11 (SIGSEGV)

Just starting to try and dig into the issue. I was wondering if anyone who is familar with the callgrind tool might have any ideas or suggestions on what the issue might be? Thanks.
