I don't. By Occams Razor it is just my first suspected cause.

Reason is that (if I understand correctly) all the memory
has been allocated before the crash, so a NULL response
from malloc is not the cause. But other than an unrelated
program crash, that basically leaves the OOM killer.

AFAIK shell (vm) limits block the allocation but do
not SIGTERM/SIGKILL the process.
