 Priority:  major               |   Milestone:

--------------------------------+-------------------------------------------
 An example of macruby 0.4 segfaulting on Fibers follows. Matt Aimonetti
 reports similar findings at http://lists.macosforge.org/pipermail/macruby-
 devel/2009-May/001717.html, including a failure to require 'fiber' in the
 0.5 branch.

 ~ % macruby -v
 MacRuby version 0.4 (ruby 1.9.1) [universal-darwin9.5, x86_64]
 ~ % macruby -e 'Fiber.new{puts"hey"}.resume'
 hey
 -e:1: [BUG] Segmentation fault
