Stdout:
terminate called after throwing an instance of 'IscDbcLibrary::SQLError'
what(): std::exception
I've investigated a problem and I think that in IscDbcLibrary::IscConnection::getCountInputParamFromProcedure function exception is thrown and in the process of stack unwinding the second exception is thrown in destuctor:
IscResultSet::~IscResultSet()
{
close();
}
After this the program is terminated.
I've fixed it by changing the destuctor IscResultSet::~IscResultSet():
IscResultSet::~IscResultSet()
{
try
{
close();
}
catch (std::exception &e)
{
fprintf (stdout, "Failed while deleting IscResultSet (exception: \"%s\")\n",
e.what());
}
catch (...)
{
fprintf (stdout, "Failed while deleting IscResultSet (unknown exception)\n");
}
}
