Well, I don't know about the problem of return status, but I
*do* know that you need to allocate some memory for
"teststring".  Both declarations above only allow teststring to
point to the location of a previously defined character (or
array thereof).  It is possible that the empty brackets
declaration finds an unallocated byte of memory and initializes
teststring to point there, thus explaining the different results 
you observed.

Why not try this declaration:
	char teststring[100];

Good luck!
