Forum: JRuby Starting with jruby getting segfaults.

Hey guys.

I am running ubuntu 12-04 it's a relatively new install. I installed
rvm and jruby-1.7.preview and also openjdk 1.7

 ruby -v
jruby 1.7.0.preview1 (ruby-1.9.3-p203) (2012-05-19 00c8c98) (OpenJDK
64-Bit Server VM 1.7.0_03) [linux-amd64-java]

I went into one my rails projects and tried to run bundle on it but it
failed on some native client gems (pg, rubyracer, twitter bootstrap
rails etc) so I commented them out.  Now when I run bundle it just
does a segfault and takes down nailgun with it.

 bundle
Fetching gem metadata from http://rubygems.org/......
[1]+  Aborted                 (core dumped) ( JRUBY_OPTS='' jruby
--ng-server 2>&1 > /dev/null )

Any clues as to what is going on?

Do you get any "hs*" files in the current dir when it crashes? Those
usually have information about what the JVM was doing when it crashed.

If you don't have one of those, it's likely it still died in native
code, but probably native code tied to JRuby rather than an extension.

Oh...open a bug so we can track this.
