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
