Quantum espresso 7.2 gives segmentation faults if compiled with OpenMP

[Crivella]

When running pw.x compiled with the QuantumESPRESSO-7.2-intel-2022b.eb config file, i always obtain a segmentation fault with the following stack trace

forrtl: severe (153): allocatable array or pointer is not allocated

This seems to be related to compiler-explorer/compiler-explorer#5483 and having OpenMP enabled, as using a newer/older enough version of the intel compiler or disabling OpenMP from the toolchain options seems to solve the problem

BTW Looking at the linked issue, this is a global problem with OpenMP and the llvm-based Intel compilers (up until the 2024 releases where the issue seems to have been fixed)
