ICE when messing with an array of method pointers

[simias]

The following code crashes with

error: internal compiler error: unexpected panic
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

    }

I cannot reproduce this with current rustc. Can you?

I can't using rustc 1.3.0 (9a92aaf19 2015-09-15), I could only reproduce it using an old rustc version I had lying around: rustc 1.0.0-beta.4 (850151a75 2015-04-30) (built 2015-04-30). It must have been fixed along the way.

I just realized I forgot to add the backtrace to my original post so here it is for posterity:

Thanks for the head's up!
