Because assert()
calls abort()
, cleanup functions registered with atexit()
are not called. If the intention of the programmer is to properly clean up in the case of a failed assertion, then runtime assertions should be replaced with static assertions where possible. (See DCL03-C. Use a static assertion to test the value of a constant expression.) When the assertion is based on runtime data, the assert
should be replaced with a runtime check that implements the adopted error strategy . (See see ERR00-C. Adopt and implement a consistent and comprehensive error-handling policy).)
See ERR04-C. Choose an appropriate termination strategy for more information on program termination strategies and MSC11-C. Incorporate diagnostic tests using assertions for more information on using the assert()
macro.

Unsafe use of abort()
may leave files written in an inconsistent state. It may also leave sensitive temporary files on the file system.
