Bug #: 55086 Summary: ICE with FORALL in allocate_temp_for_forall_nest_1 Classification: Unclassified Product: gcc Version: 4.8.0 Status: UNCONFIRMED Keywords: ice-on-valid-code Severity: normal Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: bur...@gcc.gnu.org The following program crashes in trans-stmt.c:3234's allocate_temp_for_forall_nest_1 for: 3234 unit = fold_convert (gfc_array_index_type, TYPE_SIZE_UNIT (type)); as TYPE_SIZE_UNIT(type) == NULL. ICEs in the such-marked line.
