Forum: Ruby-core YAML omap test and object id collisions

hi,

when upgrading to 1.8.6.pl369 i got reproducable testsuite failures for
the last test in test/yaml/test_yaml.rb
[[[
omap = YAML::Omap.new
1000.times { |i| omap["key_#{i}"] = { "value" => i } }
raise "id collision in ordered map" if omap.to_yaml =~ /id\d+/
]]]

this seems to be bug 3698 [1]. Disabling the GC before the test and
reenabling it afterwards fixed the failure for me. The bug is marked as
fixed but i couldnt find any reference in the changelog which revisions
should fix the issue in the 1.8 branch. Any pointers would be helpful so
i can backport the fix.

thanks in advance

  darix
