Actually there ARE a couple of problems:
- char b = "..." is attempting to assign a pointer to a character.
- char b is an automatic variable.  Destroyed when function returns.
- wr() returns a pointer.  The return(b) returns a char.  Garbage.
- the printf %s wants a pointer.  wr() returns a char not a pointer.

Not surprised the thing barfed.  Try running lint.  I'm surprised the
compiler did not complain at great lengths.  Most would.
