openssh unix dev - Jun 2002 - [Bug 293] New: sshd 3.3p1 doesn't work on Slackware

http://bugzilla.mindrot.org/show_bug.cgi?id=293

           Summary: sshd 3.3p1 doesn't work on Slackware
           Product: Portable OpenSSH
           Version: -current
          Platform: ix86
               URL: http://www.slynet.lu/
        OS/Version: Linux
            Status: NEW
          Severity: critical
          Priority: P2
         Component: sshd
        AssignedTo: openssh-unix-dev at mindrot.org
        ReportedBy: slyoldfox at bonbon.net


After compiling sshd 3.3p1 on Slackware 7.2 and Slackware 8.0
(for Slackware 7.2 with:
LIBS=-lcrypt ./configure --with-ssl-dir=/usr/local/openssl-0.9.6d --with-tcp-
wrappers
)

the sshd doesn't allow new connections even tho 3.2.3p1 does.
The error i get in /var/log/syslog is:
--
Jun 25 11:27:14 Slynet sshd[18678]: fatal: mmap(65536): Invalid argument
Jun 25 11:27:48 Slynet sshd[18682]: fatal: mmap(65536): Invalid argument

Jun 25 12:22:40 Slynet sshd[31001]: fatal: mmap(65536): Invalid argument

This happens for every incoming connection .. the connection brakes off and the 
other client closes with a 'broken pipe'

I just compiled openssh 3.3p1 with openssl 0.9.6d and zlib 1.1.4 and it
works fine for me.  The kernel is 2.4.18.  The only hitch I'm running
into is trying to get a static compile done (of at least sshd).

Here's a snippet of what strace tells me:
