Or you may add

just before the memcpy library call.
If nbyte==0 then it should be harmless, but undefined.
assert(buf || !nbyte) should catch an error situation

In C strings are pointers, in Fortran they are not.

This test case is wrong.
It dereferences thrice a NULL pointer str4.
Unfortunately -fcheck=pointer does not detect this one.
