Description Edward Tomasz Napierala freebsd_committer freebsd_triage 2018-10-25 15:16:14 UTC 
Trying to attach to a pdforked process using truss(1) kills it.  The way to reproduce:

pkg install irssi
irssi
/capsicum enter

Then, in a separate terminal, do "ps auxwd", find the PID of the irssi capsicum symbiont and "truss -p that-pid".  Notice it dying.

I tried this on head and was unable to reproduce any problems.  I believe it was fixed by commit 8e49361164e2da0e0647.
