This might be OSX-specific, then. I can't reproduce on Ubuntu with the same rustc and cargo versions.

[nerdrew]

Ya, seems probable based on some of the other open issues: #28089, #27271

[enginespot]

@apasel422 , Yes , the bug reproduced on my OS X Yosemite 10.10.5

[nerdrew]

@enginespot Did you repro using a homebrew installed version of rust?

[enginespot]

yes

I use homebrew
