This is (hopefully) something version specific, so we might be better off putting this in the easyconfig for that version rather than making it permanent here (or at least add a version guard here)

You are right. I put it in the easyconfig.

In some systems (see easybuilders/easybuild-easyconfigs#20690) MPI tests cause a Segmentation Fault.
The problem comes from a bad interaction between the dynamic library loader of the target system and the tracing of dynamic memory (malloc, calloc, free, etc.). Extrae developers are looking into it, but in the meantime, just disable dynamic memory tracing.
