In fact, the Linux kernel already has a comment about Clang's weirdness of local-bounds vs. array-bounds here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/lib/Kconfig.ubsan#n62

Yes I can confirm this. It is indeed fsanitize=local-bounds causing the kernel crash we discussed earlier. (UBSAN_LOCAL_BOUNDS=y)
