Missed runtime-constraint violation error in strtok_s

[mnd]

In the following code

slibc/src/gnu_strtok_s.c

Line 69 in e7d24f0

*ptr = (char *) memchr (token, '\0', (size_t) s1max);

if *ptr == NULL then we should trigger slibc_call_constraint_handler.

Excerpt from standard:

Runtime-constraints:
The end of the token found shall occur within the first *s1max characters of s1 for the first call, and shall occur within the first *s1max characters of where searching resumes on subsequent calls
