1 <testname=crash01> 2 <description> 3 A signal handler is set up so that in most cases the machine exception 4 generated by the illegal instructions, bad operands, etc in the procedure 5 made up of random data are caught; and another round of randomness may 6 be tried. Eventually a random instruction may corrupt the program or 7 the machine state in such a way that the program must halt. This is 8 a test of the robustness of the hardware/software for instruction 9 fault handling. 10 11 Note: Running this program just a few times, using total CPU time of 12 less than a few seconds SHOULD NOT GIVE YOU ANY CONFIDENCE in system 13 robustness. Having it run for hours, with tens of thousands of cases 14 would be a different thing. It would also make sense to run this 15 stress test at the same time you run other tests, like a multi-user 16 benchmark. 17 18 <\description> 19 <test_location> 20 ltp/testcases/misc/crash/crash01.c 21 <\test_location> 22 <\testname> 23 <testname=crash02> 24 <description> 25 A signal handler is set up so that in most cases the machine exception 26 generated by the illegal syscall, bad operands, etc in the procedure 27 made up of random data are caught; and another round of randomness may 28 be tried.
