--- Comment #12 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-15 branch has been updated by Paul Thomas <[email protected]>: https://gcc.gnu.org/g:b8cf80fd274cc88404a53762d243b059bfb5bf70 commit r15-11149-gb8cf80fd274cc88404a53762d243b059bfb5bf70 Author: Christopher Albert <[email protected]> Date: Sat Apr 11 15:13:19 2026 +0200 fortran: Fix ICE in remap_type with deferred-length character in OMP target [PR101760, PR102314] For deferred-length character types such as character(:), allocatable, TYPE_SIZE and TYPE_SIZE_UNIT contain SAVE_EXPRs wrapping the string length variable (created by variable_size in finalize_type_size). In gfc_omp_finish_clause, when computing OMP_CLAUSE_SIZE for implicitly mapped variables, the code previously used TYPE_SIZE_UNIT directly. Gimplifying this shared SAVE_EXPR resolves it in place, embedding a gimple temporary into the type's size expression. When the enclosing function is later inlined, remap_type_1 walks TYPE_SIZE and encounters the stale temporary as an unmappable SSA name, causing an ICE in make_ssa_name_fn. Fix by computing the clause size from the array domain bounds and element size rather than using the type's SAVE_EXPR directly, so that the type's size expressions remain untouched.
