#52247: rust 1.11.0 build hangs indefinitely on macos 10.12 (Sierra)

     Type:  defect     |     Status:  new
 Priority:  Normal     |  Milestone:
Component:  ports      |    Version:  2.3.4
 Keywords:             |       Port:  rust
-----------------------+--------------------------------
 I upgraded last week to macOS Sierra and found that the configure stage of
 rust 1.11.0 never completes (infinite loop).

 This appears related to a known defect fixed in the 1.12 master branch,
 currently in beta: https://github.com/rust-lang/rust/issues/35938 .
 Quoting: "The 1.11.0 compiler bootstraps from the 1.10.0 compiler, which
 is known to fail on OSX 10.12. We've backported the fix to 1.11.0 so the
 compilers we ship should work, but otherwise this is an unfortunate case
 where 1.11.0 won't be able to bootstrap on OSX 10.12."

 A fix may need to wait until 1.12 exits beta, unless 1.11.0 can be
 bootstrapped using a 1.11.0 binary off the rust site as a stage0?
