ssmtp 2.62 segfaults

[jmdeldin@…]

Hello,

I am unable to get ssmtp 2.62 to run on OS X 10.6.5. No matter what I call, I end up with a segfault:

# port uninstall ssmtp

Thank you!

Replying to jmdeldin@…:

# rm -rf /opt/local/ssmtp

Er...that should have been /opt/local/etc/ssmtp. However, it doesn't change anything because it was a vanilla ssmtp install.

Here's some more data:

(gdb) run
Starting program: /Users/russo/Temp/ssmtp/ssmtp 
Reading symbols for shared libraries +++... done

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x0000000000800008
0x00007fff880a5380 in strcmp ()
(gdb) bt
#0  0x00007fff880a5380 in strcmp ()
#1  0x00000001000014b8 in parse_options (argc=1, argv=0x7fff5fbff960) at ssmtp.c:1720
#2  0x000000010000413b in main (argc=1, argv=0x7fff5fbff960) at ssmtp.c:2075

And this is the function that is breaking everything (the if statement fails):

1720     if(strcmp(prog, "mailq") == 0) {                                               
1721         /* Someone wants to know the queue state... */
1722         paq("mailq: Mail queue is empty\n");
1723     }

here's where "prog" gets set:

2066     /* Set the globals */
2067     prog = basename(argv[0]);

Any idea what might have broken it on 10.6.5/10.6.6? I know I've had this package running before.
