[Dovecot] new crashes: is the index/mail cache endian neutral?

5 Mar 2007


      Part of our migration plan takes our users from one endianness to
another (big to little).  Will the index and mail cache files survive?  I'm
seeing some new core dumps as the first test user is migrated, which makes me
think... not.  What about if we want to build dovecot 64 bit in the future?
Will that cause problems too?
Stack trace is below the log messages.  I've edited the user's name out and
replaced it with foobar, and cleansed out a few sensitive things.
