bors cb3c4ee718 Auto merge of #86164 - FabianWolff:issue-86053, r=davidtwco ... Handle C-variadic arguments properly when reporting region errors This pull request fixes #86053. The issue is that for a C-variadic function ```rust #![feature(c_variadic)] unsafe extern "C" fn foo(_: (), ...) {} ``` `foo`'s signature will contain only the first parameter (and have `c_variadic` set to `true`), whereas its body has a second argument (a `hir::Pat` for the `...`). The code for reporting region errors iterates over the body's parameters and tries to fetch the corresponding parameter from the signature; this causes an out-of-bounds ICE for the `...` (though not in the example above, because there are no region errors to report). I have simply restricted the iteration over the body parameters to exclude `...`, which is fine because `...` cannot cause a region error.		2021-06-17 06:34:12 +00:00
