Compiles without errors but fails on linking(no FFI)

[Eilie]

Hello,

Code from https://gist.github.com/Eilie/76bca04969992e471f4d compiles just fine but fails at linking stage. Here's what I've got on #rust:

 kimundi >>> ainieco: So, its probably a combination of bugs/misuse
  in cargo and rustc where it does 
 not recompile the library you depend on, and rustc does not do enough 
 version checking to notice that it links against a old version of the lib
 without that symbol

Triage: this still happens. I've made a repo to make it a bit easier than the linked gist, with syntax updates. https://github.com/steveklabnik/rust-issue-17610

Likely a dupe of #16734 (there's a comment in #20201 that explains that bug). In this case, it is a field instead of a method but otherwise looks the same.

Ah yeah I think this is a dupe of #16734, so closing in favor of that. Thanks @jminer!
