This commit addresses an Internal Compiler Error (ICE) that occurred in GCC’s OpenMP implementation when handling map iterators with non-constant bounds. Previously, even after a ‘sorry’ diagnostic was issued for such cases, internal compiler state (elems remaining NULL_TREE) would lead to a crash. The fix involves unsetting the OMP_CLAUSE_ITERATORS flag after the diagnostic is issued, preventing the subsequent segfault.
