ecpg runtime problem

Hi,
I am using ecpg version 2.4.4. I am checking my code with purify to
remove any run time problems.
Following simple ecpg code gives core dump (when compiled with purify*).

.....
#include <stdio.h>

void main()
{
exec sql connect cdata;
}
.....

The report says
IPR: Invalid pointer read:
* This is occurring while in:
makeEmptyPGconn [libecpg.so.2.6.2]
PQsetdbLogin [libecpg.so.2.6.2]
main [t4.o]
_start [crt1.o]
* Reading 4 bytes from 0xef7a2218 between the heap and the stack.

**** Purify instrumented a.out (pid 18232) ****
COR: Fatal core dump:

* Received signal 11 (SIGSEGV - Segmentation Fault)
* Faulting address = 0xef7a2218

Please help.
Thanks in advance.
