[Bug c/37259] New: spurious warning on correct code

["tromey at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Consider this code:

int f1 (char *, char **);

int f2 (char *result)
{
  return f1 (++result, &result);
}


If I compile it with -Wall I get a warning:

opsy. gcc -Wall -c b.c
b.c: In function ?f2?:
b.c:5: warning: operation on ?result? may be undefined

However, I don't think this is undefined.

This is a regression since 4.3.
