Hi,

tdiary's amazon.rb segfault in the cause of ruby's bug.

(tdiary/lang/ja.rb):36:[BUG] Segmentation fault ruby 1.8.7 (2009-06-08 patchlevel 173) [i486-linux]

It is reported to tdiary's BTS (in Japanese).

http://www.cozmixng.org/retro/projects/tdiary/tickets/142

It is investigated by hiraku, and his blog is in Japanese.

http://www.hinet.mydns.jp/tdiary/?date=20090506#p01
http://www.hinet.mydns.jp/tdiary/?date=20090508#p01

Here is simply reproduce one liner.

ruby -ve "C=0; o=''; o.instance_eval('def m; C; end'); o.clone.m"

And hiraku points that this bug is due to below patch.

debian/patches/905_class_dup_should_copy_constants.dpatch

It is introduced to ruby1.8 1.8.7.72-3 and dropped in ruby1.8 1.8.7.173-1
because of the upstream's inclusion.

This bug is fixed in ruby1.8 development branch.
But I do not know what revision fixes it... Sorry.

Regards,
dai

r22679ではないかなと思います。
とすると#1922 http://redmine.ruby-lang.org/issues/show/1922と同じですかね。
