I encounter case when I call a stored procedure for 299166 th times (intensive, i put a non-stop while true loop to call stored procedure)
, the following exception will be thrown from PQexec. I am rather sure the exception are from PQexec, as there is a just before cout and just after cout wrap around PQexec.
std::cout << "Start PQexec " << sql << std::endl;
PGresult *res = PQexec(connection, sql.c_str());
std::cout << "End PQexec " << sql << std::endl;
const bool status = (PQresultStatus(res) == PGRES_TUPLES_OK);
PQclear(res);
"End PQexec..." is not being printed.
The last printed message before crashed is :
Start PQexec SELECT * FROM insert_unit(1,299166,array[0.407461,0.516022,0.434267
,0.802882,-1,1.99054,1.99039,0.808687], array['Pad Area','Pad Pitch','Pad Width','Pad Length','Side Pad Pitch','Package X Dimension','Package Y Dimension','Package Z Dimension'], array['mm','mm','mm','mm','mm','mm','mm','mm'])
The output is :
The thread 'Win32 Thread' (0x264) has exited with code 0 (0x0).

Using VC 2008, I break at file tidtable.c
_CRTIMP PFLS_GETVALUE_FUNCTION __cdecl __set_flsgetvalue()
{
#ifdef _M_IX86
PFLS_GETVALUE_FUNCTION flsGetValue = FLS_GETVALUE; <-- BREAK HERE
if (!flsGetValue)
{
flsGetValue = _decode_pointer(gpFlsGetValue);
TlsSetValue(__getvalueindex, flsGetValue);
}
return flsGetValue;
#else /* _M_IX86 */
Any suggestion?
