On the info page for _crt0_startup_flags, it says that this flag may
fail to lock all memory, either due to a system call error, or just
because tracking memory allocated by `sbrk' is so difficult.

Do you have any output from a crash at all? (also, is there any
specific, reliable way to tell if a program has crashed due to page
faulting within an interrupt handler?)

Bye for now,
