Maybe it's related to this comment (from ggc-page.c):
/* StunOS has an amazing off-by-one error for the first mmap allocation
after fiddling with RLIMIT_STACK. The result, as hard as it is to
believe, is an unaligned page allocation, which would cause us to
hork badly if we tried to use it. */
...or maybe not. No idea how old this comment is.
