Thanks for auditing coreutils!
A bug in sort would have been a surprise, and more of an issue,
so I've looked at it first.

Error: Null pointer dereference (CWE 476)

Function 'parse_field_count' may return constant 'NULL' at line

That is not true when the third argument to parse_field_count is
non-NULL, as is the case in sort.c from coreutils-8.5 (and in the
latest from git). In that case, parse_field_count exits upon failure
and cannot return NULL.
Thanks Jim. Incomplete analysis on my part. This is a(nother) case where
parfait is not smart enough to recognize that error is a non-returning function.
