Thanks @timholy ! Noticed in travis log:

ERROR: LoadError: size not supported for arrays with indices (0:4,1:8); see http://docs.julialang.org/en/latest/devdocs/offset-arrays/

noticed in the docs above:

To ensure that such errors are caught, in Julia 0.5 both length and size should throw an error when passed an array with non-1 indexing. This is designed to force users of such arrays to check the code, and inspect it for whether it needs to be generalized.

Ok to fix it myself?

Oh, it looks like the FFT changes haven't been backported to 0.5 yet. See JuliaLang/julia#17919

[alsam]

Ah, I see. Thanks!

[timholy]

Looks like they didn't make it into rc2 either. I could drop that last commit if you prefer, and add it back in once it's been backported.

[alsam]

No problem. I'm going to do the following:

1. merge your changes.
2. revert the last commit.
3. tag and create pull request for METADATA without last commit.
4. I could add the reverted commit later after the changes have been backported - or you what would you prefer.
   ok to go ahead?

[timholy]

Sounds great to me.

Unfortunately I'm not able to tag correctly and publish the new version.
Suspect a bug in PkgDev. Details are here:
