/** Check if any test hooks detected a problem.
*
* \note When implementing a test hook, make sure to print a message
* to standard error either at the time the problem is detected
* or during the execution of this function.
* If a problem was detected, it's ok for the calling program to keep going,
* but it should ultimately exit with an error status.
*
* \note When implementing a test hook that detects errors on its own
* (as opposed to e.g. leaving the error for a memory sanitizer to
* report), make sure to print a message to standard error either at
* the time the problem is detected or during the execution of this
* function. This function does not indicate what problem was detected,
* so printing a message is the only way to provide feedback in the
* logs of the calling program.
*
* \return Nonzero if a problem was detected.
* \c 0 if no problem was detected.
