Complete breakdown after loading a new DLL and raising an exception in it

[remittor]

The documentation says it is recommended to reuse the instance and no sense to create more than one instance.
Source: https://github.com/JochenKalmbach/StackWalker#reusing-the-stackwalk-instance
But these are fundamentally incorrect recommendations!

If, after calling the StackWalker::LoadModules, load a new DLL into the process and force the code of this DLL to raise an exception, then we will not receive a stack trace.

Example that reproduces this problem: remittor-pr@2bbd898
