Re: [Mingw-users] Crash in __mingwthr_run_key_dtors?

It was the library that encapsulated the Sqlite database API and it was configured to throw exceptions. Changing this configuration solved the problem and may also be unrelated to any static class instances outside a function. I have learned a lesson!
