Nothing has changed since the destructor was added, so the results are
the same.
Although the try/catch block is active vkSQLException is not caught:

Hi,
Let me try to describe what kind of problem I have with mingw-w64,
because it becomes a nightmare for me, despite the fact that I have over 30
years of experience with
C and c ++ compilers:
My ERP consists of a main program and two shared libraries.
(... snip ...)
#if __MINGW64__ && USECLASS == true && EXPTNTEST == false //convert struct
odbc::SQLException to
std::exception
class vkSQLException : public std::exception {
Try defining a virtual destructor for this class:
```c++
class vkSQLException : public std::exception
{
virtual ~vkSQLException();
};
// in your DLL, create a .cpp file that contains:
vkSQLException::
~vkSQLException()
{
}
```
