Greetings Hackers.
We have a reproduceable case of $subject that issues a backtrace such as
seen below.
The query that I'd prefer to sanitize before sending is <30 lines of at
a glance, not terribly complex logic.
It nonetheless dies hard after a few seconds of running and as expected,
results in an automatic all-backend restart.
Please advise on how to proceed. Thanks!
