error: aborting due to previous error


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

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

note: rustc 1.35.0-nightly (87a436377 2019-03-03) running on x86_64-unknown-linux-gnu

note: compiler flags: -C opt-level=z -C panic=abort -C debuginfo=2 -C incremental -C link-arg=-Tlayout.ld -C linker=rust-lld -C linker-flavor=ld.lld -C relocation-model=dynamic-no-pic -C link-arg=-zmax-page-size=512 --crate-type lib

note: some of the compiler flags provided by cargo are hidden

error: Could not compile `cc26x2`.

Note: I tried this on nightly 88f755f8a 2019-03-07 with the same behaviour
