Hi,

This is definitely unexpected. Can you send code that reproduces the issue?
Offlist is fine. I was unable to reproduce this.

Thanks,

I'm keep getting exception thrown saying 'Uninitialized in Library_State::algorithm_factory' when calling some method in my class from different threads. The method is for generating password salt and each time a new AutoSeeded_RNG object is created. First call to method works fine, but when another thread calls this method, an exception is thrown. I went through little debugging of botan library and I found out that somehow the global_lib_state object is set to zero on second attempt of creating AutoSeeded_RNG object. I have solved this temporarily by creating AutoSeeded_RNG private member of my class and for now it works fine.
