I've got three reproducible rc17 crashes, all fixed in dovecot-20070117.tar.gz, and I've managed to get the same crashes in Solaris 10 on Sparc. However, Solaris 10 has walkcontext() so I've been able to use versions with the memdebug-* patches. The memdebug-delayed.diff version doesn't crash or log anything interesting, but the memdebug-bof.diff version does:

memdebug-bof.diff had the possibility to notice it, but it should have logged an error in that case. Your backtraces show that it crashed so it didn't detect the overflow. Anyway, I think that's still somewhat expected because it wasn't exactly ordinary buffer overflow.
