Respond to review comments: use mutex to protect building of vector of crash printers.
Create a global vector of crash printers that the signal handler uses to report the IRs in the event of a crash.
Adding a crash printer and removing it from the vector is protected using mutex locking.

Respond to review comments:  change test to use not --crash and make it check for part of IR.
