Is Travis broken on nightly?

I have several packages updated for 0.7 that are mysteriously failing on Travis:

https://travis-ci.org/MikaelSlevinsky/FastTransforms.jl/jobs/398816686
https://travis-ci.org/JuliaMatrices/LowRankApprox.jl/jobs/405078206

Is this a known issue?

I just had a (very simple) job run without trouble on what appears to be the same Julia version as yours. Maybe there is an issue with precompilation on the nightly?

On Appveyor it crashes due to OutOfMemory:

https://ci.appveyor.com/project/MikaelSlevinsky/fasttransforms-jl/build/1.0.73/job/ablm48bip7mbafvj

Maybe it’s the same issue just on Travis it is less descriptive?
