        * gimple-fold.c (gimple_fold_call): Do not remove lhs of noreturn
        calls if the LHS is variable length or has addressable type.
        If targets[0]->decl is a noreturn call with void return type and
        zero arguments, adjust fntype and remove lhs in that case.

        * g++.dg/opt/pr71210-1.C: New test.
