orc unwinder: stack-out-of-bounds accesses

2017-10-18 Thread Dmitry Vyukov
Hello, I am seeing lots of KASAN-detected stack-out-of-bounds accesses in the new ORC unwinder. Examples of reports below. linux-next on a7dd40274d75326ca868479c62090b1198a357ad. You can reproduce this by enabling CONFIG_KASAN with gcc7+ (which supports stack instrumentation). ==
