Hi,

using libv8 3.16.14.9 on travis breaks a build. Using libv8 3.16.14.7 does not break the build. I'm not sure if it's the fault of libv8, but at least it seems to be a fix to use an older version of the library. The Gemfile can be found here. The Gemfile.lock is only available on travis. It is not part of the build. Any other information you need to help me?

The the log can be found here. It segfaults:

CSS and Javascripts which are minify shouldn't be re-minified .../home/travis/.rvm/gems/ruby-2.2.0/gems/therubyracer-0.12.2/lib/v8/context.rb:99: [BUG] Segmentation fault at 0x00000000000000

It's not just Travis. On my local (OSX Yosemite) system I get errors even trying to compile libv8 3.16.14.9:

gem install libv8 -v '3.16.14.9'

ERROR:  Error installing libv8:

Happens on ruby 1.9.3-p547 and 2.1.2.

Gem version 3.16.14.7 still works fine. Error suggests spaces.h is performing bogus comparison.

I've yanked this version of the gem until I can find out what's going on.

@atz I still cannot understand why rubygems is not matching yosemite to the binary gem 😠 You should not be having to ever compile libv8 for yourself.

Thanks a lot. @ignisf I didn't found the *.h-file you mentioned in the travis output. Maybe you've got a different problem than me?
