smaller and simpler testcase
In cp_simplify_init_expr(), we are lowering part of the return
statement for the lambda function from this:
*NON_LVALUE_EXPR <this> = TARGET_EXPR <D.2173, <<< Unknown tree: aggr_init_expr
4
__comp_ctor
D.2173
NON_LVALUE_EXPR <this> >>>>;
into:
<<< Unknown tree: aggr_init_expr
4
__comp_ctor
*NON_LVALUE_EXPR <this> <-- notice we've dropped D.2173
NON_LVALUE_EXPR <this> >>>;
This last blob cannot be stored into retval because the value of the
aggr_init_expr is a read from the constructor which has a void return type.
