Bug #1302: Strange behavior of callcc
http://redmine.ruby-lang.org/issues/show/1302

Author: Christophe Calves
Status: Open, Priority: Normal
Category: core, Target version: 1.9.1
ruby -v: ruby 1.9.1p0 (2009-01-30 revision 21907) [x86_64-linux]

The code runs "[0].map" with a block which uses callcc to stop the execution of map and return the continuation. Later this continuation is called three times with three different values. The expected behavior is that these calls should result in three different computations. Each computation being the mapping with the corresponing value. Instead, the result is very strange.
