Build errors through failure

[mpapierski]

Apologizes if this is incorrect repo to report such things. Probably I should report in both affected repos.

I'm using failure = 0.1.3 and after cargo update backtrace got resolved to 0.3.10 which is released today. And all of sudden I can't build failure because:

   Compiling failure v0.1.3

Looks like backtrace introduced some backwards incompatible change, or failure needs to be updated to accomodate for changes in backtrace.

For now cargo update -p backtrace --precise 0.3.9 solves the build issue, but as I'm developing a lib crate my travis builds will fail.

Could reproduce the same issue in a minimal environment (the default cargo new-
hello world with extern crate failure and failure="0.1.3" in Cargo.toml)

FYI rust-lang-deprecated/failure#279

I'm going to close this since I believe it was fixed with 0.3.11

@vlisivka are you perhaps using an outdated rustc? If not, mind opening a dedicated issue with some more info?
