gcc - Ruby 1.8.6 `gem install` segfaults with "abort trap 6" -


i can't install gems on fresh rbenv-installed ruby 1.8.6 on mountain lion. gem install segfaults , shell prints "abort trap: 6":

$ rubylib= rubyopt= bash  $ gem install --verbose bundler   http://rubygems.org/latest_specs.4.8.gz   302 moved temporarily   http://production.s3.rubygems.org/latest_specs.4.8.gz   304 not modified   installing gem bundler-1.3.5   abort trap: 6

there similar issues reported answer of them need use non-apple gcc 4.2 build such old version of ruby. doesn't apply me, since i've installed gcc brew install apple-gcc42 , rbenv install process picked up, evident below:

$ gem env rubygems environment:   - rubygems version: 1.3.7   - ruby version: 1.8.6 (2010-09-02 patchlevel 420) [i686-darwin12.3.0]   - installation directory: /users/mislav/.rbenv/versions/1.8.6-p420/lib/ruby/gems/1.8   - ruby executable: /users/mislav/.rbenv/versions/1.8.6-p420/bin/ruby   - executable directory: /users/mislav/.rbenv/versions/1.8.6-p420/bin   - rubygems platforms:     - ruby     - x86-darwin-12   - gem paths:      - /users/mislav/.rbenv/versions/1.8.6-p420/lib/ruby/gems/1.8      - /users/mislav/.gem/ruby/1.8   - gem configuration:      - "gem" => "--no-ri --no-rdoc"   - remote sources:      - http://rubygems.org/  $ ruby -rrbconfig -e 'puts rbconfig::config["configure_args"]'   '--prefix=/users/mislav/.rbenv/versions/1.8.6-p420'   'cc=/usr/local/bin/gcc-4.2'   'cflags=  -wno-error=shorten-64-to-32'   'ldflags=-l'\\''/users/mislav/.rbenv/versions/1.8.6-p420/lib'\\'' '   'cppflags=-i'\\''/users/mislav/.rbenv/versions/1.8.6-p420/include'\\'' '  $ /usr/local/bin/gcc-4.2 --version   i686-apple-darwin11-gcc-4.2.1 (gcc) 4.2.1 (apple inc. build 5666) (dot 3)

the difference can see @ glance installed gcc-4.2 /usr/bin , used /usr/local/bin. shouldn't make difference, suppose it's possible makefile hardcoded /usr/bin (which more common - guess?) gcc.

since mentioned used homebrew install gcc-4.2, i'll add used manual method, following these instructions: http://caiustheory.com/install-gcc-421-apple-build-56663-with-xcode-42. again don't think should make difference, never know.

kineticjs - draw multiple lines and delete individual line -
