It works fine for me, I just upgraded to 0.25.1 and I'm on a Mac.

Where are you running crystal spec? What's the source code?

Perhaps it was related to cache (which got rebuild on 2nd run?), previous binaries or sth like that. Still, it shouldn't segfault though.

Where are you running crystal spec? What's the source code?

no 1: raven.cr
no 2: money
no 3: retriable.cr

raven.cr spec's are running good for me on Sierra.

Do you happen to be using OS X El Capitan? We have been having some issues there.

Yes, I do (10.11.6).

😞

We've been discussing El Capitan on Homebrew/homebrew-core#29527. It seems things weren't that well anyways.

We should follow up on crystal-lang/distribution-scripts#14

have you tried rm -Rf ~/.cache/crystal?

@RX14 yep, it "fixes" 2 out of 3 errors I've posted, the last one still remains.

With master (#6261 ty) we have some different backtrace, if that helps:
