Hi Igor,

Could you please suggest us, how to look forward with this.

Thanks,
Agneeswaran

Pasting earlier post.

Hi Igor, 

We have debugged our code, as the core dump refers to SQLGetDiagRec()
function. 

We are using this particular function to do the error validation,Yes
previously TextLengthPtr was assigned to NULL pointer. 

while (SQLGetDiagRec(hType, 
                hHandle, 
                ++iRec, 
                (SQLCHAR*)wszState, 
                &iError, 
                wszMessage, 
                (SQLSMALLINT)(sizeof(wszMessage) / sizeof(CHAR)), 
                /*(SQLSMALLINT *)NULL*/ &len) == SQL_SUCCESS) 
        { 
       ... 
          } 

With/Without the above code the concurrent test is failing.And we are
getting the following error message for failed process. 

[HY000] Failed to run map query remotely. (0)

There is no core dump file is generated after we changed from NULL pointer
in SQLGetDiagRec(). 

Please let us know, how to debug further on this. 

Thanks,
