I see that the library SO version number is 2. That's probably log4cplus
1.0.2. Please try with the latest 1.0.4 release candidate instead. If it is
repeatable, try to distil a testcase out of the code. And/or compile with
debugging information and try to find out the reason for the access
violation. The call stack below does not look familiar and I do not remember
any bugs related to LogLevelManager any other relevant part of the call stack.
