You need to insert v into the basic block before the return. Note that %calltmp is absent from the dump of the function. The verifier is complaining because it found this pointer to %calltmp, but it didn't find the definition anywhere above its use.

Don't you have the same problem with other atoms, e.g. variable names? This sounds like something that should be implemented in the language's runtime library.
