It's mentioned in <support/check.h>, but it's somewhat buried:

/* Record a test failure.  This function returns and does not
   terminate the process.  The failure counter is stored in a shared
   memory mapping, so that failures reported in child processes are
   visible to the parent process and test driver.  This function
   depends on initialization by an ELF constructor, so it can only be
   invoked after the test driver has run.  Note that this function
   does not support reporting failures from a DSO.  */
void support_record_failure (void);

I'm not entirely sure what the consequences are when the framework is
used from an auditor.  Surely support_record_failure won't work.  But
FAIL_EXIT1 and similar ways of process termination should probably
reveal the test failure.  Full cleanup of temporary files will not run.

Thanks,
Florian
