            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).
