Following up on this issue, the library compiled with VC 2011 beta doesn’t exhibit the issue so it has to be related to MinGW or something. I’m definitely not an expert in the area but if somebody have weird multi thread behavior on Windows and knows how to fix it with the MinGW build, we’d be glad to hear :)

It seems that FastBit works perfectly fine in a single thread application but almost systematically crashes when i run concurrent queries. This issue doesn’t exists in Linux so i’m starting to think that it could be related either to the pthread port or the windows specifics (compilation, ...). Did you have some use case involving concurrency on Windows ? Would you mind sharing a 64bits fastbit.dll (1.3.0) built with VC to see if i can reproduce the issue ?
