Not sure why this is segfaulting on Travis. It works fine for me locally (on 0.4.0-dev+3804). @vtjnash any idea what I did wrong?

[stevengj]

Yes, I've been having problems with Travis that I can't reproduce locally too...

[simonster]

Yes, I made (or at least tried to make) the changes @vtjnash suggested there.

[simonster]

I can actually reproduce the segfault locally on JuliaLang/julia@1915c50, which is what's running on Travis, but not on current master. So it may be a bug that has been fixed.

The nightly has been updated and the Travis builds now pass.

Thanks!
