Failing energy minimization with 2023.2+gcc on apple silicon

Hi!

That definitely looks to be worthy of a bug report.

As a check, could you please recompile GROMACS with -DGMX_SIMD=None and see if it helps? And share your input files?

I have tried to run the tests for the installation, but this doesn’t work (this has been reported before).

Could you please share the link to this report?
