+ * How to catch an assert:
+ * - save a jump buffer where execution will resume after the assert
+ * - setup a handler for the abort signal, call longjmp within
+ * - optional - close stderr ( fd 2 ) to discard the assert message
+ *
+ * Unity also does a longjmp within its TEST_ASSERT* macros,
+ * so the macro below restores stderr and the prior abort handler
+ * before calling the Unity macro.
