Comment (by Ionic):

 This workaround doesn't allow full package installation as of rust 0.27.0
 any longer.

 Instead, cargo is now failing with a stack overflow error in `main`.

 So far, I've tried upgrading the external cargo dependency to the newest
 version (0.28), as well as forcing the system to use the already installed
 cargo version (naturally we can't do this in general as that would create
 a dependency loop; I was merely desperate and interested if it would work
 with that), but all my attempts were futile.
