Do you have short code to reproduce it, and what platform?
Or if it is reproducible, then run that application from debugger.
`.gdbinit` for gdb is bundled with the source, break at the line and try `rp` macro to see the content of `orig` and `shared`.

I have the exact same problem and message. Wish I had more to add, but I don't. I came on to add an issue and saw Felix beat me to it.  I'll follow this issue and participate as I can.

I do not have code to reproduce it but I'm trying to provide you with a snippet today.

OS X 10.11.2

Confirming for me also. I have traced the problem to this line:

https://github.com/rails/rails/blob/v4.2.5/actionpack/lib/action_dispatch/routing/route_set.rb#L546

in the call to name.to_s.match(/^[_a-z]\w*$/i). Specifically, when match() is called.

The strange thing is that when I substitute name.to_s.freeze.match(/^[_a-z]\w*$/i) then it passes without the core dump failure.

The other thing is that this line doesn't always fail, it only fails on some routes. I have no idea why, because the name is always a string class, and a valid string. 

Ruby 2.3.0
Rails 4.2.5

As Felix says, this is no a problem with Ruby 2.2.4.
