Better code searching for Debian

I know its a feature because I switched some code from strncpy to strlcpy because profiling showed writing the zeros into an 8KB URL string buffer was wasting a LOT of time.

If you are worried about information leaks then you need to be using a security library and it needs to be written in ASM because compilers are too likely to optimize all the security features away. For example, unless a value is volatile the compiler can remove all writes to it if nothing reads it before destroying it.
