Abort trap

https://github.com/indirect/jquery-rails/blob/master/lib/generators/jquery/install/install_generator.rb#L34

"get" with github https, maybe?

(It's really weird that the segfault only happens with gem 'pg')

Im also getting a segmentation fault but i dont have the 'gp' gem. I think is something related with 'https'. Im trying to do a get with an 'https' and I always have the same problem, even if i've tried with different ways to do the Get. Im gonna try using an older version of Ruby.

If you find a solution please let me know!

I also have this problem!! Any solution would be much appreciated!

I think the problem is in the ruby libraries. I checked my code in another laptop and it works perfeclty. I tried to delete ruby versions but in the end i decided to format my mac and start from the beginning (i also had another weird erros...)

Now is working for me with Ruby 1.9.2 and Rails 3.0.5. Good luck!!

Hi, I am facing the same issue. Did anyone happen to find a solution? Thanks in advance

Temporarily removing pg from Gemfile worked for me. =/

Just to add to the body of knowledge here, I ran into this error as well and commented the pg gem from Gemfile as mikeoligny had suggested, and without re-running bundle install, everything worked exactly as it was supposed to. This is odd because I ran into the same segmentation fault error with Devise a few days ago, also with http.rb.

Same problem here too, also using PG but if I comment it out of the Gemfile (no re-bundle) it blows up with a 'where the heck is PG' type error :(

Looks like this bug: http://redmine.ruby-lang.org/issues/4611

FWIW I'm also getting this error, Mac OS X Snow Leopard with PostgesQL84 installed via MacPorts, with gem 'pg' in my Gemfile it blows up with the same segfault, without it works perfectly.

Is anyone who is experiencing this problem connecting using 'https'? I suspect this is caused by conflicting versions of OpenSSL: if the version that's linked against your libpq is not the same as the one linked against your Ruby stdlib's openssl extension, there's bound to be problems.

PS- on MacOS X, you can check the shared libraries something is linked against using 'otool':

Looks like you're spot on!

Okay, thanks @jeromewilson. Anybody else?

If this is indeed the problem, then I should probably try to detect it in the extconf, or ideally at runtime, and output a warning. There's a ticket open in the 'pg' bugtracker for this issue; comments and/or suggestions are welcomed either here or there.

Not sure if this is of any help but I had the same issue and the otool just kept pointing me to different libssl versions every time. I just copy pasted the gem 'pg', :require => 'pg' to the bottom of the Gemfile and it worked.

Hope it helps!!!
