OMG WTF BBQ
Certainly -DNDEBUG should never be used unless upstream explicitly say
that it's intended to be supported, and usually not even then.
Pretty much the only reason to use it is if it is necessary to disable
time-consuming checks, but most upstreams are more sensible than to
throw the assert() baby out with the expensive consistency check
bathwater.
