Subject: Re: passwdqc code quality
btw. I suspect that this error with memset resulted from the use of
LTO. Owl uses an old compiler, so this error could not occur.
Unfortunately, gcc-4.7.4 is the last compiler, which does not apply
aggressive and unsafe optimization. The worst part is that these types
of errors are very difficult to detect and probably need to use
fuzzers like Michal's AFL:
