Manipulating x64 Unwind Info To Match Assembly Hook

Some calls cause stack unwinding, though no C++ exception is thrown

I use Visual Studio Native Unit Test Framework for C++. When an assertion fails, next statements aren't executed and local objects destructors are called, so it seems like an exception is thrown, but I can't catch any C++ exception by catch (...)…

Say I have two C++ functions foo1() and foo2(), and I want to minimize the likelihood that that foo1() starts execution but foo2() is not called due to some external event. I don't mind if neither is called, but foo2() must execute if foo1() was…
