| | | | | | | | | | | | | | | | result (GH-101339) (#101340) [3.11] gh-99952: [ctypes] fix refcount issues in from_param() result. (GH-100169) Fixes a reference counting issue with `ctypes.Structure` when a `from_param()` method call is used and the structure size is larger than a C pointer `sizeof(void*)`. This problem existed for a very long time, but became more apparent in 3.8+ by change likely due to garbage collection cleanup timing changes..

| | | | | | | | | | | | | | | | (GH-99046) In very rare circumstances the JUMP opcode could be confused with the argument of the opcode in the "then" part which doesn't end with the JUMP opcode. This led to incorrect detection of the final JUMP opcode and incorrect calculation of the size of the subexpression. NOTE: Changed return value of functions _validate_inner() and _validate_charset() in Modules/_sre/sre.c. Now they return 0 on success, -1 on failure, and 1 if the last op is JUMP (which usually is a failure). Previously they returned 1 on success and 0 on failure.
