------- Comment #19 from steven at gcc dot gnu dot org 2006-01-14 15:17 ------- On AMD64, EMPTY_FIELD_BOUNDARY is 64 bits, so if we honnor that for the zero-length bitfield, we get a size of 12 for the struct in the test case in comment #9 (where we apparently expect 8, which is what you get with EMPTY_FIELD_BOUNDARY==32 even on AMD64).
