Any idea on what's causing this?

Description: imap process crashed with SIGBUS.

Versions: OS: Solaris 8, 9 Dovecot: 1.0-test57 Gcc: 3.2

Configure options: env CC=gcc CFLAGS="-O -g" ./configure
--prefix=/var/dovecot
--disable-ipv6
--with-ssl=openssl
--with-ssldir=/etc/ssl
--with-passwd-file
--without-bsdauth
--without-checkpassword
--without-pam
--without-passwd
--without-shadow
--without-vpopmail
--without-static-userdb
--without-libiconv-prefix
--with-storages=mbox
--with-pop3d

Interestingly, eliminating optimisation seems to get rid of the
problem, suggesting it might be a compiler problem.  I've also tried
gcc flags "-m32", "-m64", "-O3", "-O2", "-O1" and configure options
"--with-file-offset-size=32 --with-mem-align=4" with no relief.
