No.

I'm not sure why people are having trouble understanding this.

The test in question is not valid C.  It is entirely erroneous, and
should be deleted.  Merely computing the value "(void *)-1" is allowed
to perform LITERALLY ANY ACTION AT ALL, including turning your
computer into a frog.  The compiler is free to implement this as a
call to abort() if it chooses.  Testing this is nonsensical.
