Comment:
Here's the relevant bit of code:
{{{
if (ret == (void *)-1) {
if (errno == ENOMEM ||
(errno == EINVAL && sizeof(void*)==4 && size >= 0xc0000000)) {
// If we request more than 3Gig, then we get EINVAL
// instead of ENOMEM (at least on Linux).
errorBelch("out of memory (requested %lu bytes)", size);
stg_exit(EXIT_FAILURE);
} else {
barf("getMBlock: mmap: %s", strerror(errno));
}
}
}}}
Perhaps we're getting `EINVAL` under different circumstances. I didn't
manage to reproduce it (yet).
