Вы надеетесь на сегфолт ?

Кстати, у нас везде же по умолчанию overcommit memory.

malloc(3):

By default, Linux follows an optimistic memory allocation strategy. This
means that when malloc() returns non-NULL there is no guarantee that the
memory really is available. In case it turns out that the system is out of
memory, one or more processes will be killed by the OOM killer. For more
information, see the description of /proc/sys/vm/overcommit_memory and
/proc/sys/vm/oom_adj in proc(5), and the Linux kernel source file
Documentation/vm/overcommit-accounting.
