The value of 'ctype->bit_size' is set to 1 for booleans which confuses the i386 backend: ./compile allocate.c compile: compile-i386.c:1406: emit_binop: Assertion `0' failed. Aborted Looking at the code, we assume that "bit_size / 8" gives a sane result on various places. This patch fixes the problem by bumping bit_size to 8 for booleans. This also makes sizeof(_Bool) return 1 which is consistent with what GCC 4.4.3, for example, does.
