The debian-private mailing list leak, part 1. Volunteers have complained about Blackmail. Lynchings. Character assassination. Defamation. Cyberbullying. Volunteers who gave many years of their lives are picked out at random for cruel social experiments. The former DPL's girlfriend Molly de Blanc is given volunteers to experiment on for her crazy talks. These volunteers never consented to be used like lab rats. We don't either. debian-private can no longer be a safe space for the cabal. Let these monsters have nowhere to hide. Volunteers are not disposable. We stand with the victims.

Wouldn't filtering of strace output work just as well for this?  And
if you're looking for buffer overrun errors then you might well want
to look into trying out my package Checker.  It points out all writes
(or reads) beyond the end of a dynamically allocated buffer.
Admittedly this doesn't help with static buffers, which are generally
the problem.
