I've never seen anything this bad, and it gave me a hearty laugh out
loud.  I guess in my years people mostly self select toward safer
languages if they are human fuzzers.

This, I thought was odd, as it had been there FOREVER and was well tested.   I brought up the source code system and checked it anyhow and found the afore mentioned programmer had checked in one change:   he deleted the "free" call in it.
