imap.authenticate(‘LOGIN’,‘dom’,‘mypassword’)
imap.examine(‘INBOX’)
imap.search([‘SINCE’,‘01-Jan-2000’]).each do |msg_id|
puts msg_id

end

This code will cause Ruby to core dump with a bus error after a number
of fetches. The number is not constant. Garbage collector acting up, or
am I at fault?

No, it’s a bug, either in one of the included packages (socket, monitor,
digest/md5 or openssl) or a bug in Ruby itself. If I were a betting
man, I’d
bet on monitor (synchronize), but that’s a guess.

Which version of Ruby, btw? The Changelog indicates that there were a
few
touchups since 1.8.2.
