Hi!
The whole topic of GCC PR94358 "[OMP] Privatize internal array variables
introduced by the Fortran FE" is yet to be resolved, but we may already
now add Gergő's testcase:

... to document the status quo, and so that it may help highlight any
behavioral changes later on. I've pushed "Add
'libgomp.oacc-fortran/pr94358-1.f90' [PR94358]" to master branch in
commit d1ba078d9bcc3457d36ba12695cfef29eb3ca942, see attached.
