Reason for closing:  Works for me
Additional comments about closing:  Based on a private email, this only happens with a custom LLVM pass (where the issue probably lies).

The real error is the "Invalid function argument type" and the missing space in the producer string is correct.

You'll need to provide a full reproduction example, since I can't repro with something like "int main() {return 0;}".
