No, not a bug in the compiler.  A bug in your code, in K&R as well as
ANSI standard.  A pointer is not the same as an array.  The code on
the right could work if you declared a global pointer named Test and
initialized it in the main program to point at the start of the global
array Test before calling testfn.

On a second thought, I think you will have to give the pointer a different
name from Test, but then it should work as desired.
