[Bug fortran/32362] New: ICE - gfortran in lookup_decl_in_outer_ctx, at omp-low.c:1508

["longb at cray dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Description:
This test case derived from OpenMP test omp1/F2_2_9h.f90, involves nested
parallel loops.  The gfortran compiler currently aborts with an internal
error for this code.

> gfortran -v
