Description of problem:
It seems that Fortran compiler is emitting incorrect symbol/debug information or the debugger is failing at parsing those

Every time we have to load debug symbol generated by Intel Fortran


Version-Release number of selected component (if applicable):
devtoolset-8-gdb-8.2-2.el7.x86_64

Additional Information:

It seems that Intel provided fixes already, but I can't find upstream information
