segmentation fault with sendmail 8.13.0 on debian


I just finished building sendmail 8.13.0 with BerkeleyDB 4.2.52, Cyrus SASL 2.1.18 and OpenSSL 0.97d on Debian with a 2.4.20 Kernel.

After I solved some problems the Build -c and Build install completed without errors but when I start sendmail I get a segmentation fault.

The output of

/usr/sbin/sendmail -d0.1 -bv root


Version 8.13.0
Segmentation fault

Starting sendmail without parameters works but when using any parameters I get the segfault.

I'm kinda desparate now. I spent some hours getting the whole thing to build and now I just dont know what to do about the segfault.

Can anyone help me what to do about this or where to look for problems?

Thanks for any help.

According to this thread it might be a memory problem.

thanks for the reply.

I think its unlikely that it is a memory problem since I got 500mb ram thats only 1 or 2 years old and there is about 100mb ram free.

but I will check if there are memory errors.

In my less than vast experience, seg. faults often occur on null pointers, which can mean a config file is missing, or unreadable. Config files are complicated.
/var/log/maillog may give some idea of the specific complaint.
You might also tail -f /var/log/maillog in a separate terminal while initiating sendmail.

I think I'm on the right way now.
I checked the mail.log and mail.err but these contained no output at all. So I searched the sendmail man page for debug settings and set debug level to almost maximum. The last line before the seg fault reported setting an option "DaemonPortOptions". I checked this and found no apparent errors but commented out the line in the Now sendmail runs without the seg fault but since the option is almost surely important I have to fix it somehow.
But thats a easier thing to look for, so for now, thanks folks.

To finish the thread: I got a line in sendmail.conf thats working with

O DaemonPortOptions=Port=25, Name=MTA

and seg faulting with

O DaemonPortOptions=Port=smtp, Name=MTA

I think it shouldnt matter but as this doesnt make any difference to me, I will leave it at that.

Again, thanks for helping.

Sounds like someone removed the line for SMTP from /etc/services
