[Mono-list] One Bug, Many questions

Ok, its a jit bug (or unsupported feature). The problem is that the
current jit does not handle the case when there are value types on the
runtime stack at basic block boundaries, for example

ldfld x (where x is a struct)
br target (please notice that the stack is not empty, it contains x)

maybe you can avoid such constructs in your code? I will also try to
find a real solution for the problem.
