Subject: [ruby-talk:10207] Re: POLS question: returning from a closure

Another callcc surprise is:

irb(main):001:0> c=nil
nil
irb(main):002:0> callcc{|c|}
nil
irb(main):003:0> c.call
nil
/usr/local/lib/ruby/1.7/irb/ruby-lex.rb:229: [BUG] Segmentation fault
ruby 1.7.0 (2001-01-23) [i386-freebsdelf4.2]
Abort (core dumped)

Don't ask me what my intention was! :-)
