--- Comment #11 from Jeffrey A. Law <law at redhat dot com> --- Martin, A lot of folks use "delta" to do testcase reduction. Delta is pretty dumb in that it removes code, runs a test (defined by the developer) and if the failure is still there, removes more code, else restore and remove something else and iterate. As such it's common for tests to have undefined behaviour if they were to be run. But even a testcase with undefined behaviour shouldn't ever ICE or segfault.
