Subject: [ruby-core:38072] [Ruby 1.9 - Bug #4320][Closed] Bus Error in digest/sha2 on sparc


Issue #4320 has been updated by Hiroshi Nakamura.

Status changed from Assigned to Closed

I applied the last patch to trunk at r32546 and ruby_1_9_3 at r32547.

Nils, sorry for not merging your patch directly. The reason I didn't apply yours is almost from the size of the patch. Would you please report the issue to the upstream (http://www.aarongifford.com/computers/sha.html) for other users, and of course for us?

 Most likely this is caused due to misaligned memory. Any comment is greatly appreciated.
 
 This bug can reproduce at Ruby 1.8, too.
 
 ruby -e "require 'digest/sha2'; d= Digest::SHA256.new; ['a' * 97, 'a' * 97].each {|i| d.update(i)}; p d"
