# REQUIRES: x86-registered-target

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