However, the test doesn't always segfault, causing the test to run a # single time. # # This patch fixes the test by putting it within a loop and jumping, via # setcontext, just prior to the loop in case it segfaults. This way we get the # desired behavior (run the test COUNT_MAX times) regardless if it segfaults or # not. This also reduces the use of setcontext for control flow logic, keeping it # only in the segfault handler. # # Also, since 'count' is changed within the signal handler, it is declared as # volatile to prevent any compiler optimization getting confused with # asynchronous changes. # # Signed-off-by: Gustavo Luiz Duarte # Signed-off-by: Michael Ellerman # Link:
