I am seeing the same error message in my application, under what might be similar circumstances. I just downloaded the latest available build (6.7.13), but the error keeps appearing.
I've already spent a day just trying to reproduce this problem in a smaller project, but with no success so far. I've noticed that it only happens when connected to SQL Server Compact databases, and this error doesn't consistently happen either (sometimes the same query will work just fine). It also seems to only happen when I'm directly running my application, as opposed to running it inside C++ Builder with the debugger.
I'm hoping the fix you provided this other customer might work for me as well. Is it possible to get the same custom build so I can try it out too?
