Note: This is a regression fix. The attached patch regression tested on x86_64. This one is fairly simple. I will commit shortly. Regards, Jerry fortran: Allow task-reduction allocatable scalars without outer ref [PR102596] OpenMP task reduction lowering can call gfc_omp_clause_default_ctor for an allocatable scalar with outer == NULL_TREE. That is valid for scalar allocatables that only need fresh storage allocation and do not need a copied descriptor or allocatable-component walk. The Fortran hook asserted unconditionally on outer != NULL_TREE, so reduction(task, +:r) with an allocatable scalar ICEd during omplower. Fix this by requiring outer only for the cases that actually use it: descriptor-based allocatables and types with allocatable components. Keep the assertion for those cases and allow NULL outer for plain scalar allocatables. Add a regression test for the allocatable task-reduction case. gcc/fortran/ChangeLog: PR fortran/102596 * trans-openmp.cc (gfc_omp_clause_default_ctor): Only require an outer reference when the constructor path actually uses it. gcc/testsuite/ChangeLog: PR fortran/102596 * gfortran.dg/pr102596.f90: New test.
