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.
