Hi,

I want to ask what does the error message mean by
"0x40023abb in resetPQExpBuffer () from /usr/local/pgsql/lib/libpq.so.3"?
I got this message using GDB to trace the program.
(Segmentation fault occurswhen run the program directly.)

I reviewed the program many times, and found this is only to happen when
I call the `ctime()'  or `time()' in a program function.

code fragment FYI
--8<------------------------
// `res = PQexec(conn, sql)' here..
...
...
  }
  else if (!strcmp(PQfname(res, i), SYNCTIME_FIELD_NAME))
  {
//   puts("7");
   //char chP[30];
   printf("timer=%ld\n", time(timer)); // <====== without this line, the
program works
//   printf("%s", ctime(time(NULL)));
//   printf("%s", asctime(localtime(&timer)));
   sprintf(tmp, "'1999-12-11 09:50:58'::timestamp, ");
   strcat(p2, tmp);
  }
  else if (!strcmp(PQfname(res, i), SERVERID_FIELD_NAME))
  {
   puts("8");
   sprintf(tmp, "'%s'", PQgetvalue(res, 0, i));
   strcat(p2, tmp);
  }
 }
...

Thank you very much.
