MacOS test name generation with INSTATIATE_TEST_SUITE_P not resolving pointers on macos-latest image runner

[QuinnCuijpers]

Describe the issue

Using INSTANTIATE_TEST_SUITE_P's optional variable for generating names from the provided pointers through a user-defined function works on windows-latest and linux-latest through GitHub workflows, but on macos-latest, it returns the pointer itself

Steps to reproduce the problem

The issue occurs in the GitHub workflow starting from at least https://github.com/QuinnCuijpers/dandan/actions/runs/24250482647/job/70808176430 up to https://github.com/QuinnCuijpers/dandan/actions/runs/24253827508/job/70820074987

Note that I do not think it's macos specific. We've found the same failure in #4956, and # GetParam() stuff should not be in the test name on linux either
