This only happens when the macro NDEBUG was undefined when <assert.h> was last included.RETURN VALUENo value is returned.CONFORMING TOISO9899 (ANSI C). In the 1990 standard, expression is required to be of type int and undefined behavior results if it is not, but in the 1999 standard it may have any scalar type.BUGSassert() is implemented as a macro; if the expression tested has side - effects, program behaviour will be different depending on whether NDEBUG is defined. This may create Heisenbugs which go away when debugging is turned on.SEE ALSOexit(3), abort(3)
