We are just trying to bring up a new server and chose to use Dovecot

just testing with some throw away accounts using squirrelmail. I can

This happens always? For all users?
Program terminated with signal 10, Bus error.
Signal 10 usually means unaligned memory access or accessing mmap()ed
file past the end of file.
#0 0x000aa19c in mail_index_map (index=0x489, type=0) at
/usr/local/src/dovecot/dovecot-1.2.12/src/lib-index//mail-index-map.c:502
502 map->hdr = *hdr;
..
hdr = (const struct mail_index_header *) 0x8000000
This hdr alignment looks ok. Also I can't really figure out from the
code how it could be crashing here. And -O2 has optimized the backtrace
and some variables in a way that it's a bit difficult to figure out
what's actually going on.
Could you compile without -O2 (but I think -O is required or it won't
crash)? Easiest way would be to do something like:
1. cd src/lib-index/Makefile
2. Change -O2 to -O in Makefile
3. make clean && make
4. cd ../imap && make && make install
Then it would be helpful to know at least the output of:
bt full
p hdr
p *hdr
p &map->hdr
p *map->rec_map
OK. Steps 1-4 completed without any problems.
Does it happen with all users? We are just in the development, immediate
pre-transition stage. We had hoped to bring the server up early this
week. At the moment, I only have a couple of users we are playing with.
I used my account with only a minimal amount in /var/mail/chrisho based
on playing on this machine. Then I copied my /var/mail from the server
we are going to replace. It is substantially larger, but I have no
trouble with it using uw-imap on that server. I placed it on this
server, did an `rm -r ~chrisho/mail` to give a clean start on that, and
then connected with squirrelmail. I've repeated this same process, back
and forth. Interesting thing is that when I did it this morning, after
the steps 1-4 above, I was clicking all over in squirrelmail with my
smaller /var/mail/chrisho and couldn't cause any errors. Then I logged
out, swapped in the larger /var/mail/chrisho, rm'd ~chrisho/mail, and
reconnected with squirrelmail. It brought up my inbox without any
errors. However, when I clicked on a message, it core dumped.
gdb output is below.
