Failure to compile on nightly 2018-01-27

[Bert-Proesmans]

I updated my nightly compiler this morning to "rustc 1.25.0-nightly (7d6e5b9da 2018-01-27)" and received the error below when trying to compile this library. I cannot say with certainty that this compile error happens since this exact version because i only update once every few days.

error[E0277]: the trait bound `syntax::<unnamed>::FatalError: std::marker::Send` is not satisfied

   |                   `syntax::<unnamed>::FatalError` cannot be sent between threads safely

   = help: the trait `std::marker::Send` is not implemented for `syntax::<unnamed>::FatalError`
   = note: required by `std::rt::begin_panic`
   = note: this error originates in a macro outside of the current crate (in Nightly builds, run with -Z external-macro-backtrace for more info)

Edit: i wasn't complete with my information. The same error is thrown for each call to the panictry macro at lines 61, 66, 72, 86.

That is the cause of this issue probably, i will file a PR to fix this

I was just about to post an issue about this when I found this one. Solved it temporarily by replacing FatalError with "fatal error" so at least I'm not blocked.
