1 /* This testcase originally provoked an unaligned access fault on Alpha.
3 Since Digital Unix and Linux (and probably others) by default fix
4 these up in the kernel, the failure was not visible unless one
5 is sitting at the console examining logs.
7 So: If we know how, ask the kernel to deliver SIGBUS instead so
8 that the test case visibly fails. */
