Description

=begin
Hi,

The following script causes the interpreter to crash on SPARC.
It is likely to be caused by a mix of continuation and GC.

<---
GC.start
require 'continuation'
o = Object.new
def o.to_ary() callcc {|k| @cont = k; [1,2,3]} end
GC.start
begin
if [10, 20, 1, 2, 3, 30, 1, 2, 3, 40] != [10, 20, o, 30, o, 40].flatten
puts "FAIL1"
exit(1)
end
GC.start
puts "OK"
rescue => e
p e
else
puts "AA"
o.instance_eval {@cont}.call
end
GC.start
--->
Script output:
<---
OK
AA
#<RuntimeError: flatten reentered>
*** glibc detected *** ruby1.9: free(): invalid pointer: 0xf7f2aa54 ***
Aborted
--->

It fails both with:
ruby 1.9.0 (2008-06-20 revision 17482) [sparc-linux]
and
ruby 1.9.1p0 (2009-01-30 revision 21907) [sparc-linux]
=end
