[fpc-pascal] MS SQLConn - Possible memory leak in driver (dblib or libiconv2)

[LacaK]

Hi Marcos,
First useful thing would be isolate source of memory leak.
If it is on FreePascal side, then we must search there, if it is on 
FreeTDS side, then we must report bug to FreeTDS project.
You can use version of dblib.dll, which does not use libiconv2, so we 
can isolate it.
Do you not use any other 3rd party libraries or other components in your 
project, which can cause mem leaks ?
