How to terminate a program when it crashes? (which should just fail a unit test instead of getting stuck forever)

Question

Our unit tests fire off child processes, and sometimes these child processes crash. When this happens, a Windows Error Reporting dialog pops up, and the process stays alive

Answer 1

Try setting

HKCU\Software\Microsoft\Windows\Windows Error Reporting\DontShowUI

to 1. (You can also set the same key in HKLM, but you need admin privs to do that.)

This should prevent WER from showing any UI.
