In terms of the flags themselves, they probably shouldn't be present in
production builds -- the assert()s themselves technically have a tiny
performance penalty (because of the compares and branches), but it's
probably not measurable.
On the other hand, it's not going to *fix* anything. The assert()
statements are present to enforce the contract between the application
and the library. If an assert() is halting the process, it's because the
application using the stack has a bug in it. The assert() should help
catch the bug earlier rather than later.
In other words: simply adding -DNDEBUG to the compile *won't* *fix* the
problems David and Sunitha are having; it will just make them more
inscrutable and harder to track down.
