If I exclude CZoneInfoDatetimeSubclassTest[test_folds_from_utc] from the pytest run, the free() error does not happen.

zoneinfo 0.2.1 with #101 and #115 applied.

Hmm, this does not happen outside of the build service virtual machine.

Might be influenced by some of the MALLOC_* variables set inside
