I thought about this, ideally we could insert an artificially-created object file with more than 3 symbols right before we ran it with JIT. But  IIUC llvm-exegesis currently lacks such functionality (I think using snippet file as input doesn't exercise this program path) so it would be difficult to write a test at this moment.
