mrsh/builtin/set.c -rw-r--r-- 5.8 KiB
ensure argv passed to getopt is NULL terminated

This has two fixes, 1: in push_frame allocates an extra array
element, and uses calloc instead of malloc to ensure that element is
NULL.  2: in argv_dup, enough memory is allocated but, the last element
is left uninitialized.  By using calloc instead, the last element is
guaranteed to be NULL.

I also added a test for this, although it does not always fail since it
relies on undefined behavior.
