Description

small.c is an example on the base of maycast-int-bad.c
which exposes bug in may aliases:
verdict unsafe if res = lock(data);
verdict safe if lock(data);

the hypothesis is that function call with return value is not properly matched in process_one_edge of bddptsto.ml

I do not observe this anymore. Perhaps, it was fixed during the work on new aliasing algorithm.
