Hi, all. I'm trying to push another app to Heroku & `bundle install` is telling me there's a bug: `/Users/dobbin/.rvm/gems/ruby-1.9.3-p0/gems/json-1.6.5/ext/json/ext/json/ext/parser.bundle: [BUG] Segmentation fault ruby 1.8.7 (2011-12-28 patchlevel 357) [i686-darwin10]` That is the tail of the error message; I've a full crash report (I'm using OS X 10.6.8 in this particular instance) & I've tried to register at the relevant Ruby site for bugs but their mail bot must be having a day off. I've drawn a blank on Google also. Has anybody else seen this? As you can see, I'm using the latest stable rvm, Ruby 1.9.3-p0 & rails 3.2.1. Any help appreciated.

Why does it mention both Ruby 1.8.7 and 1.9.3? If you're using native gems compiled for 1.9.3 with 1.8.7, no wonder you're getting segfaults. -- Matma Rex > **ยทยทยท** > > 2012/1/31 Phil Dobbin \: > > > `/Users/dobbin/.rvm/gems/ruby-1.9.3-p0/gems/json-1.6.5/ext/json/ext/json/ext/parser.bundle: > > [BUG] Segmentation fault > > ruby 1.8.7 (2011-12-28 patchlevel 357) [i686-darwin10]`
