FIX: Unhandled exceptions occur in an application when the application uses the SQLGetPrivateProfileString function and the ODBC_BOTH_DSN configuration mode in Microsoft Data Access Components (MDAC) 2.8

The SQLGetPrivateProfileString function is a Microsoft Open Database Connectivity (ODBC) function in Microsoft Data Access Components (MDAC) 2.8. When an application uses the SQLGetPrivateProfileString function, some internal memory allocations become corrupted. Additionally, unhandled exceptions occur in the application when the following conditions are true:

• Both the system data source name (DSN) and the user DSN are requested by using the ODBC_BOTH_DSN configuration mode.
• The size, in characters, of all the user DSNs is less than the size of the buffer that is passed to the SQLGetPrivateProfileString function.
• The total size, in characters, of the system DSN and the user DSN is larger than the size of the buffer that is passed to the SQLGetPrivateProfileString function.
