#211 Unable to build with gcc 11 - Segmentation fault

[Bug Menot]

The package can be built and/or 'pip install'ed under Python 3.10 and gcc 10.
However, trying to 'pip install' or build it from source under Python 3.10 and gcc 11 fails. This seems to be an issue with gcc 11 and/or optimization settings. I can NOT change the version of Python or gcc, since those are the only versions supported under OpenWrt 22.03.5.
