[BUGS] libpq incompatibility

[Admin Gaston]

Hi, sorry my english. Recently i was using postgresql 7.2, and then i update to 7.3.3. We was running a C program that was working fine with 7.2, but in 7.3.3 it seg fault.   int procesarConsultasSQL(int nCliente){     .......... more code     FD_SET(cli->socketDB, &readfds);     timeout.tv_sec = timeout.tv_usec = 0;     select(cli->socketDB + 1, &readfds, NULL, NULL, &timeout);     if (FD_ISSET(cli->socketDB, &readfds)){         if (PQconsumeInput(cli->conn)){             if (!PQisBusy(cli->conn)){                 while ((cli->res = PQgetResult(cli->conn)) != NULL){                     //procesamos los datos devueltos por la base de datos, ya sean                     //select's o update's y lo agregamos en la cola de envio del cliente                     switch(PQresultStatus(cli->res)){                         ....... more code                     }                     ....... more code                     PQclear(cli->res);                 }                 ........ more code             }         }     }     ....... more code } When the program is running for a while, it finish with segmentation fault (core dumped).   #0  0x420742e2 in _int_malloc () from /lib/tls/libc.so.6 #1  0x4207360b in malloc () from /lib/tls/libc.so.6 #2  0x400278b3 in PQmakeEmptyPGresult () from /usr/lib/libpq.so.3 #3  0x40028387 in PQconsumeInput () from /usr/lib/libpq.so.3 #4  0x400282f1 in PQconsumeInput () from /usr/lib/libpq.so.3 #5  0x4002886a in PQisBusy () from /usr/lib/libpq.so.3 #6  0x0804c3dc in procesarConsultasSQL(int) () #7  0x0804cfe0 in main () Is this a know bug?, or the way i am programming this isn't correct? Any help is aprecciated, and thanks to Tom Lane for my other problem, it was solved.   Regards, Tavella Gaston.
