Trying to start up Julia 1.0 (from the released binaries) on OSX, and it immediately seg faults:

```julia

```

Any ideas?

That’s scary. Corrupted download maybe?

I tried to download again just a few min ago, same problem.

Do you have any sort of startup file that would try to load some code or anything else unusual about your environment? We did test the OS X release binaries on a couple of Macs before putting them up on the website, so I don’t think they’re broken for everybody, but would be good to figure out what triggers this.

I think I fixed it → in my bash\_profile I had this:

```julia
export PATH="/Applications/Julia-0.7.app/Contents/Resources/julia/bin:$PATH"
export JULIA_BINDIR="/Applications/Julia-0.7.app/Contents/Resources/julia/bin"

```

I commented those out, and now 1.0 starts up fine. I’m wondering if it was setting the JULIA\_BINDIR env variable.

Setting that still shouldn’t cause Julia to segfault. Could you file a GitHub issue with as much info about how to reproduce?
