> Release build exits right after printing:
> Calling Reporter
> Debug build now is falling with assertion. But last year (in december) when I started
the investigations it was also failing at the same point with SIGSEGV somwhere in managed
code.
> Investigations shows that the problem was in Ia32StackInfo and Ia32StackLayout.
> Wrong types of some variables led to incorrect value in 'rsp' register after context
restoration before exception hadler entering.
