…r#6718) * PythonAPI: Fix segfault in GetAvailableMaps When using CARLA with Python 3.10, I'm getting a segfault in GetAvailableMaps. The problem disappears when PyList manipulation does not happen with GIL unlocked, as done in this commit. The initial part of crash backtrace (from GDB) is below: Program terminated with signal SIGSEGV, Segmentation fault. warning: Section `.reg-xstate/49253' in core file too small. #0

We fix it by releasing the GIL only for the actual libcarla call and constructing Python objects with GIL locked. --------- Co-authored-by: bernat <bernatx@gmail.com>
