title: Can I kill another process from SIGSEGV handler?
body: <p>Background: I'm fuzzing a long-lived process with afl-fuzz by passing to it the filename to process from a stub that afl-fuzz runs for each sample.</p>
  
  <p>When the long-lived process crashes via SIGSEGV, I want the stub to also generate a SIGSEGV, so that afl-fuzz will mark the sample as interesting.</p>
  
  <p>Will calling <code>kill(stub_pid, SIGSEGV)</code> from the long-lived process's SIGSEGV handler work ?</p>
