There is a compiler error with GCC 12 discussed here: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115824 This Pybind code triggers the bug and was causing our compiler tests to fail. To fix gem5 compilation for gcc 12 these warnings/errors have been suppressed for this code. This is a copy and paste of: pybind/pybind11#5355 Change-Id: I9344951ef00d121ea0b609f4faa13dfe09aabb3b

Issue: pybind#5224 The `internals.registered_types_py...` line in pybind11.h triggers a false-positive bounds checking warning in GCC 12. This is discussed in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115824. The workaround implemented is taken from suggestions then refactored to use the `PYBIND11_WARNING_PUSH` and `PYBIND11_WARNING_POP` MACROS.

Your replies are lightening fast compared to my own :). I'm very impressed with Pybind's response to my fix given i'm an outsider to the project. Thank you for the feedback. I've reduced the comment. |

I think I've added this correctly. I just update the PR description here, right? |
