Use rust 1.32.

Use rust 1.32.

If that is you best answer, then my feeling is that bug 1521734 needs to be backed out until it works with the latest stable version of rustc.

You can also use the patch attached to this bug, or build with --without-thumb.

Thanks "ac_add_options --without-thumb" worked for me.

I will wait for a properly reviewed path to land before removing this from my .mozconfig.

I was expecting the version that was queued to fail to land with a conflict, but it didn't. The current version of the patch, updated after that was what I actually meant to land.
