I’m new to Ruby, so I may be doing something wrong, but the following
code continually gives me a core dump (Illegal instruction: 4 (core
dumped)) in both irb and ruby. I’m running versions:
ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-freebsd6]
feed-normalizer (1.3.0)
require ‘rubygems’
require ‘open-uri’
require ‘feed-normalizer’
feed = FeedNormalizer::FeedNormalizer.parse
open(‘reddit: the front page of the internet’)
feed.each {|line| print line, " "}
Ideas?

Can someone confirm this so I know if it’s my ruby compilation or not?

Why? Ruby shouldn’t core dump. Ever. Either ruby has a bug or a
binary extension does.
Did you do something freaky when you built your ruby?
If you can reproduce the error, rerun like so:
% gdb ruby
r script.rb
blah blah
BOOM!

I am using Ruby 1.8.6 for Windows and would like to use that version of
Ruby from the cygwin bash prompt.I have added the following to my
.bashrc:
alias ruby=’/cygdrive/c/ruby/bin/ruby.exe’
alias erb=’/cygdrive/c/ruby/bin/erb.bat’
alias gem=’/cygdrive/c/ruby/bin/gem.bat’
alias fxri=’/cygdrive/c/ruby/bin/fxri.bat’
alias gem_mirror=’/cygdrive/c/ruby/bin/gem_mirror.bat’
alias gem_server=’/cygdrive/c/ruby/bin/gem_server.bat’
alias gemhelp=’/cygdrive/c/ruby/bin/gemhelp.bat’
alias gemwhich=’/cygdrive/c/ruby/bin/gemwhich.bat’
alias irb=’/cygdrive/c/ruby/bin/irb.bat’
alias rake=’/cygdrive/c/ruby/bin/rake.bat’
alias ri=’/cygdrive/c/ruby/bin/ri.bat’
alias testrb=’/cygdrive/c/bin/testrb.bat’
alias update_rubygems=’/cygdrive/c/ruby/bin/update_rubygems.bat’
alias iconv=’/cygdrivec/ruby/bin/iconv.exe’
alias rubyw=’/cygdrive/c/ruby/bin/rubyw.exe’
I was trying to run the simple Tk app from Programming Ruby:
#!/cygdrive/c/ruby/bin/ruby -w
require ‘tk’
root = TkRoot.new { title “Ex1” }
TkLabel.new(root) do
text ‘hi there’
pack(‘padx’ => 15, ‘pady’ => 15, ‘side’ => ‘left’)
end
Tk.mainloop
I am able to run the program from the Dos prompt, but the program hangs
when run from the cygwin prompt.
So far programs not using Tk have run okay from cygwin.
Any suggestions on what I can check would be appreciated.
TIA,
Kevin
Hi,
What’s concerned with core dump using feed-normalizer?

Seems you use non-cygwin ruby but cygwin Tk dll might be
loaded.

It’s a long stack trace, so I’ve posted only part of it. I can
provide the complete trace if needed.
