This bug was initially reported on Stackoverflow by "JensS": https://stackoverflow.com/questions/77523793/python-crashes-pymem-debugrawfree-when-querying-mariadb-with-sqlalchemy-2-0
When running the attached script in Python Development Mode it crashes when substituting parameters inside the where clause:
Debug memory block at address p=0000028AE6179E20: API 'r'
|
21 bytes originally requested
|
The 7 pad bytes at p-7 are FORBIDDENBYTE, as expected.
|
The 8 pad bytes at tail=0000028AE6179E35 are FORBIDDENBYTE, as expected.

Data at p: 4d 79 20 41 63 63 6f 75 ... 00 00 00 00 00 00 00 00
