If you get the full list and it segfaults (or whatever) afterwards it does sound like memory/stack corruption but assuming you are using the new version I sent you yesterday I cannot explain why.

Not sure it will really help but you can limit the number of DSNs returned by adding something like:

if (numDataSources > 100) {
   break;
}

just after fDirection = SQL_FETCH_NEXT. If you restrict the number returned and the crash goes away you might be able to identify the entry that causes corruption.
