[LLVMdev] Value not in slotcalculator! error

This is my first post to llvmdev (reading for about a month) so I apologize if I'm not following protocol.

I'm writing a Common Lisp compiler using LLVM with the C++ API and I'm experiencing a problem that I have not been able to solve by myself.

I'm getting a "Value not in slotcalculator" when I write out bitcode for a module that I generated.

It happens the second time that I compile the same source code - the first time everything works fine and the functions all verify fine.

Here's what I know: when I dump the value that seems to be responsible for the error:

input>> call V->dump()
output>> declare void @_Unwind_Resume(i8*)

Now the funny thing is I don't call this function, it gets inserted into my code when I generate a "resume" instruction using IRBuilder::CreateResume for exception handling.  I've tried adding a declaration for _UnwindResume myself but that doesn't do anything.

Any help would be appreciated.
