I doubt the problem is in the upstream changes between .3 and .12. I'm more worried about the build option changes. SQLite has a lot of Windows-specific code in it, plus some Cygwin-specific code, too. The build changes override some things to force it to believe it's being built for a more generic POSIX type system. It may be both things: the build option changes that force more I/O calls to go through Cygwin instead of direct to the Win32 API could be tickling BLODA bugs. Yet another possibility is that the build option changes cause a subtle ABI change that will be fixed when SVN is rebuilt against it. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
