[Dovecot] dovecot crash on sendfilev64 on solaris 8 (32bit)

[Fabio Pietrosanti (naif)]

Hi,

i'm running dovecot on a SMP sparc 32bit server with solaris 8(latest patch
installed).

Dovecot with ssl.
Postfix+imap+maildrop .

Dovecot work fine with every email and folders delivered by maildrop, but now
i'm trying to move all my local folders (i'm using mutt and i'm storing my
emails locally on my pc) to the imap server .


The upload of an entire 12000 mails folders worked fine, when i try to access
that folder i can see "fetching headers" and all it's ok but when i attempt to
read a message dovecot imap process crash.

Dovecot crash even if i attempt to read one single email moved from my local
inbox to remote imap INBOX maildir.

Dovecot work fine on every folder created by maildrop.

I made some debugging with truss and found that he die on sendfilev64 call:

I noticed that maildir files created by dovecot have the following file names
format:

1075891040.P3168Q12514M511660.supertolla.itapac.net:2,S

and maildrop one are in this other format:

1075893689.M267966P5215V01540032I001B6706_0.supertolla.itapac.net,S=1381:2,S

I'm working on SPARC 32 bit architecture with the following compile options:

    CC=gcc
     CXX=gcc
     CFLAGS="-O9 -msupersparc -mcpu=supersparc -mtune=supersparc -fno-omit-frame-pointer -m32"
     CXXFLAGS="-O9 -msupersparc -mcpu=supersparc -mtune=supersparc -felide-constructors -fno-exceptions -fno-rtti -m32"
     CPPFLAGS="-I/usr/local/ssl/include/ -I/data/chroot/mysql/mysql/include/mysql"
     LDFLAGS="-L/data/chroot/mysql/mysql/lib/mysql -L/usr/local/ssl/lib"
     LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/ssl/lib:/data/chroot/mysql/mysql/lib/mysql

     export CC CXX CFLAGS CXXFLAGS CPPFLAGS LDFLAGS LD_LIBRARY_PATH
     ./configure --prefix=/dovecot --without-passwd --without-passwd-file --without-shadow --without-pam \
      --without-ldap --without-vpopmail --without-pgsql --without-cyrus-sasl2 --with-ssl=openssl \
      --with-ssldir=/etc/ssl --without-pop3d --with-mysql --with-static-userdb

     vi config.h

     #define PASSDB_MYSQL 1
     #define USERDB_MYSQL 1

     vi src/auth/Makefile

     add -lmysqlclient to LIBS
     LIBS =  -lsocket -lnsl -lrt -lsendfile -lmysqlclient
