My immediate attention is at #5 0x0804c81a in trace (level=5,
formatstring=0x807119a "%s,%s: executing query [%s]") at debug.c:93
Line 93 is a call to vsyslog.
My guess is that argp is null or even worse, uninitialised.
Try adding an if(argp) before using argp like this:
void trace (int level, char *formatstring, ...)
{
va_list argp;
va_start(argp, formatstring);
if (level <= TRACE_LEVEL)
{
if (TRACE_VERBOSE != 0)
{
vfprintf (err_out_stream, formatstring, argp);
if (formatstring[strlen(formatstring)]!='\n')
fprintf (err_out_stream,"\n");
}
if (TRACE_TO_SYSLOG != 0)
{
if (formatstring[strlen(formatstring)]=='\n')
formatstring[strlen(formatstring)]='\0';
if (level <= TRACE_WARNING)
{
/* set LOG_ALERT at warnings */
if(argp)
vsyslog (LOG_ALERT, formatstring, argp);
}
else
if(argp)
vsyslog (LOG_NOTICE, formatstring, argp);
}
if(argp)
va_end(argp);
}
/* very big fatal error
* bailout */
if (level == TRACE_FATAL)
exit(EXIT_CODE);
if (level == TRACE_STOP)
exit(EXIT_CODE);
}

John

This seems to suggest a bug in the trace() function in debug.c Problem
is.. I can't seem to find what's wrong. For clarity, I'll print
the function below. Can anybody find anything that's wrong?
void trace (int level, char *formatstring, ...)
{
va_list argp;
va_start(argp, formatstring);
if (level <= TRACE_LEVEL)
{
if (TRACE_VERBOSE != 0)
{
vfprintf (err_out_stream, formatstring, argp);
if (formatstring[strlen(formatstring)]!='\n')
fprintf (err_out_stream,"\n");
}
if (TRACE_TO_SYSLOG != 0)
{
if (formatstring[strlen(formatstring)]=='\n')
formatstring[strlen(formatstring)]='\0';
if (level <= TRACE_WARNING)
{
/* set LOG_ALERT at warnings */
vsyslog (LOG_ALERT, formatstring, argp);
}
else
vsyslog (LOG_NOTICE, formatstring, argp);
}
va_end(argp);
}
/* very big fatal error
* bailout */
if (level == TRACE_FATAL)
exit(EXIT_CODE);
if (level == TRACE_STOP)
exit(EXIT_CODE);
}
Currently, I'm a bit lost here..
Sandino, could you try recompiling with TRACE_TO_SYSLOG (in debug.c) set
to 0 (zero), and running again. Maybe there's an error earlier in the
code, which will show up in a different place when not tracing to
syslog.
BTW, I'm also sending this to dbmail-dev
