Subject: [ruby-core:27959] Re: [Bug #2330] Non systematic segmentation 	fault with autoload rubyspec

1) The minimal test case
I wonder why I didn't copy-paste my actual original code. In any case,
the bug happens if the instance method #load is redefined in any way
(and not the module method, as in my posted example). Thus the file
'load.rb' should read:

module Kernel
  def load
  end
end
generate_any_exception

I'm very sorry about the confusion.

2) Switch of binary versions.
The Snow Leopard compiled binary will not run on Leopard at all. I get:
dyld: unknown required load command 0x80000022

The Leopard compiled binary runs (of course) on Snow Leopard, and will
also segfault (most of the time, in the same way as the binary
compiled on snow leopard)

$ rubydev load_test.rb
test.rb:5: [BUG] Bus Error
ruby 1.9.2dev (2010-01-29 trunk 26470) [i386-darwin9.8.0]


Let me know what additional tests I can do to help pinpoint the issue.
