   3 ## If a process spawns llvm-symbolizer, and wishes to feed it addresses one at a
   4 ## time, llvm-symbolizer needs to flush its output after each input has been
   5 ## processed or the parent process will not be able to read the output and may
   6 ## deadlock. This test runs a script that simulates this situation for both a
   7 ## a good and bad input.
