Please submit a full bug report, with preprocessed source.
Please include the complete backtrace with any bug report.
See <file:///usr/share/doc/gcc-12/README.Bugs> for instructions.
Preprocessed source stored into /tmp/ccSEyJuT.out file, please attach this to your bugreport.
```

Other data points:
1) lowering the optimisation from -O3 to -O2 avoids the internal compiler error
2) using gcc-11/g++-11 (with -O3) instead og gcc-12/g++-12 does not cause any issue.

Best regards
