------- Comment #3 from seongbae dot park at gmail dot com 2006-06-26 21:08 ------- The immediate cause of the problem is in stor-layout.c:place_field():
1118 if (DECL_SIZE (field) != NULL 1119 && host_integerp (TYPE_SIZE (TREE_TYPE (field)), 0) 1120 && host_integerp (DECL_SIZE (field), 0)) 1121 rli->remaining_in_alignment 1122 = tree_low_cst (TYPE_SIZE (TREE_TYPE(field)), 1) 1123 - tree_low_cst (DECL_SIZE (field), 1); For the field "d", remiaining_in_alignment becomes negative after line 1121-1123 - because the DECL_SIZE is larger than TYPE_SIZE for "d". -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28160
