ruby -v:
ruby 2.1.0dev (2013-10-09) [x86_64-darwin12.5.0]
[ruby-core:57736]

Description

this code causes "Segmentation fault: 11"

o1=Object.new
o1.extend(Comparable)
o2=Object.new
o2.extend(Comparable)

begin
p Range.new(o1,o2) # raises Stack Error
rescue SystemStackError
end

begin
p Range.new(o1,o2) # Segmentation fault: 11
rescue SystemStackError
end

i tested also other ruby versions:

Crashs for versions:
ruby 2.1.0dev (2013-10-09) [x86_64-darwin12.5.0]
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin12.3.0]
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]

works for versions:
ruby 2.1.0dev (2013-09-22 trunk 43011) [i686-linux]
ruby 2.0.0p247 (2013-06-27) [i386-mingw32]
ruby 2.0.0p0 (2013-02-24 revision 39474) [i686-linux]

from what i can see it looks like an 64bit problem on MRI

it seems to work on rubinius 64bit
