Do you at least have a repro? Here’s one, but from a different lineno than the original poster (and probably a different OS): > ruby 1.8.4 (2005-12-24) [powerpc-darwin8.6.0] > > Abort trap No core, alas.

For what it’s worth, I’ve had trouble all day when rubygems runs rdoc on gems. I blew away 1.8.4 and reverted to the 1.8.2 that comes with OSX Tiger. With 1.8.4, I got: > Installing RDoc documentation for rake-0.7.1… > RDoc failure in lib/rake.rb at or around line 42 column 10 > The internal error was: > > ERROR: While executing gem … (TypeError) > can’t convert Fixnum into String > Installing RDoc documentation for rake-0.7.1… > ERROR: While executing gem … (NoMethodError) > undefined method `text’ for -517611318:Fixnum > Installing RDoc documentation for rake-0.7.1… > Error in template: private method `gsub!’ called for -517611318:Fixnum > Original line: -517611318 On 1.8.2, all went well. Rdoc generation also worked for zentest and watir, which had both failed before. The Zentest errors I gave earlier in this thread. The watir error was this: > Installing RDoc documentation for watir-1.4.1… > RDoc failure in readme.rb at or around line 63 column 3 > The internal error was: > > ERROR: While executing gem … (TypeError) > can’t convert Fixnum into String * * * Brian M., independent consultant Mostly on agile methods with a testing slant [www.exampler.com](http://www.exampler.com), [www.testing.com/cgi-bin/blog](http://www.testing.com/cgi-bin/blog) ---

We’ve partially fixed it on the 1.8 branch in CVS, but it is still there (just a lot less–feels like 60-80% less). I’ve found that rdoc seems to push it more. It probably generates a lot more symbols than most programs. I’ve found that if you keep running the rdoc command, it’ll eventually generate everything and be fine. Not good, I know, but better than rolling back to stock 1.8.2 in many situations.
