SUMMARY: AddressSanitizer: 72000 byte(s) leaked in 1 allocation(s).

CPython versions tested on:

CPython main branch

Operating systems tested on:

Linux

Untersuche die Allokation in Python/optimizer.c:981 in _PyJit_TryInitializeTracing und verfolge ihre Bereinigungspfade. Reproduziere das bereitgestellte Threading-Beispiel mit LeakSanitizer und überprüfe anschließend, dass die 72.000-Byte-Allokation freigegeben wird und der Leak-Bericht nicht mehr erscheint.
