Pavel Afremov commented on HARMONY-2890:
----------------------------------------

The source of the bug is in incorrect check in cpp_set_last_frame, for the case when m2n created in the heap instead stack.

> Currently the smoke test exception.FinalizeStackTest fails on msvc release build.
> It prints the message: 
> "Unwinding:  Lost lastFrame"
> and exits.
> To reproduce the issue please build the drlvm in release mode and run the test in the following way:
> <drlvm home>\bin\java -cp <path to smoke tests classes> exception.FinalizeStackTest
> Since the function which prints the warning is described as "a hack function to detect problems with C++ object living on while destructive unwinding is used" in drlvm\trunk\vm\port\src\lil\ia32\pim\stack_iterator_ia32.cpp, possibly it is worth investigating and fixing.
