Okay, so can you please document that -fstack-check probes one extra page ahead by design, skipping one page adjacent to current stack pointer on the assumption that callers are also compiled with -fstack-check and therefore must have probed that page previously? I think an indication that this option is intended for use with Ada also would help.
