Geant3 quite broken on (our CI) macOS

[ChristianTackeGSI]

It looks like geant3 is even more broken on macOS then it was before:

Note: We're repeating a failing test 6 times to make sure it's not some random error. This seems to help on all our linux machines. But it seems that it does not help on our macs.

@fuhlig1 @karabowi Could you check if you see what the issue here is please? Not familiar with what geant3 should be doing. Thanks!

To be more specific. The problem arouse from the latest clang versions. On my clang version 14.0.3 newest FairSoft+FairRoot run smooth.

I checked the issue already some time ago. The problem appears when Geant3 (Zebra) tries to book memory.
It looks like something with the memory management of macosx has changed which results in the observed problems.

Since the problem is deep inside the Fortran code for the memory management it would need some time to find the problem. Before spending that time we should check if running Geant3 on macosx is a use case we need to support.

Also see with Ivana if the problem is already known.
