I am getting segmentation faults on a SLES10 system with 1.25 built
from the official sources. Here's the backtrace and some information:
Program terminated with signal 11, Segmentation fault.

The code in question looks like this:
1628 fprintf(SMTPS.pMsgFile, "RCPT TO:<%s> {ra=%s}\r\n",
SMTPS.pszSendRcpt,
1629 (SMTPS.pszRealRcpt != NULL) ?
SMTPS.pszRealRcpt: SMTPS.pszSendRcpt);
So it's pretty obvious, that pMsgFile being a NULL pointer is the
reason for the crash.
