clang++ agrees with g++ here. The lambda expression needs to be instantiated
so that it can be evaluated and expressions in discarded statements are not
instantiated.

Rewriting code as

int int_val = -(int)float_val;
avoids bug.
And rewriting code as
double float_val = ;
int int_val = -float_val;
also avoids bug.
