18* This sample test aims to check the following assertions:
19*
20* If SA_SIGINFO is set in sa_flags and Real Time Signals extension is supported,
21* sa_sigaction is used as the signal handling function.
22
23* The steps are:
24* -> test for RTS extension
25* -> register a handler for SIGABRT with SA_SIGINFO, and a known function
26*   as sa_sigaction
27* -> raise SIGABRT, and check the function has been called.
28
29* The test fails if the function is not called
