example for failed structure propagation
In attached file there is an example of invalid calculation where, a structure
with integer is manipulated inside a function call which takes struct as
pointer and same integer member is part of arithmetic result operation.
The issue was tested on several compilers 4.6.3, 4.7.2, 4.8.1 on different
platforms Linux and Windows with same result.
