-Subject: [PATCH 12/15] Ignore broken and non-applicable tests
-
-c-link-to-rust-va-list-fn: unstable feature, broken on aarch64, #56475
-env-funky-keys: can't handle LD_PRELOAD (e.g. sandbox)
-long-linker-command-lines: takes >10 minutes to run (but still passes)
-simd-intrinsic-generic-bitmask.rs: broken on BE, #59356
-sparc-struct-abi: no sparc target
-sysroot-crates-are-unstable: can't run rustc without RPATH

+Subject: [PATCH] Increment `self.index` before calling
+ `Iterator::self.a.__iterator_get_unchecked` in `Zip` `TrustedRandomAccess`
+ specialization
+
+Otherwise if `Iterator::self.a.__iterator_get_unchecked` panics the
+index would not have been incremented yet and another call to
+`Iterator::next` would read from the same index again, which is not
+allowed according to the API contract of `TrustedRandomAccess` for
+`!Clone`.
+
+Fixes https://github.com/rust-lang/rust/issues/81740
+
