[Bug tree-optimization/39202] [4.4 Regression] internal compiler error: in collapse_rest_of_var, at tree-ssa-structalias.c:3296

In
              lhs.var = collapse_rest_of_var (lhs.var);
              rhs.var = collapse_rest_of_var (rhs.var);
rhs.var points into the middle of lhs.var chain, so the first call sets
collapsed_to to lhs.var and the second finds it already non-0.
