Bug ID: 59134 Summary: Infinite loop between store_fixed_bit_field and store_split_bit_field with STRICT_ALIGNMENT Product: gcc Version: 4.9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: middle-end Assignee: unassigned at gcc dot gnu.org Reporter: jules at gcc dot gnu.org Compiling code using packed structures with a single non-zero-sized element and a zero-sized array can lead to segfaults due to stack exhaustion on STRICT_ALIGNMENT targets (at least PowerPC E500 targets are affected).
