This would mean losing the local-bounds coverage. I tried to test it without local-bounds and with a locally defined array on the stack and it works fine (the handler is called and the error reported). For me it feels like --array-bounds and --local-bounds are triggered for the same type of undefined_behaviours but they are handling them different.
Er, if --array-bounds still works on local arrays, what does local-bounds actually do? >_> :P If we don't have a reduction in coverage, yeah, I'm fine to turn that off. -- Kees Cook _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
