    = note: this error: internal compiler error originates in the macro `clone_resetable` (in Nightly builds, run with -Z macro-backtrace for more info)

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md
