Hi Paul, code->expr1->symtree->n.sym->ts = code->expr2->ts; + /* Sometimes the selector expression is given the typespec of the + '_data' field, which is logical enough but inappropraite here. */

Bizarrely, since the fix for pr101625, the testcase compiles and runs correctly with s/select type (y => x)/select type (y => (x))/ ! The fix is straightforward and appears to be one of those wrinkles arising from the use of associate variables as a selector. The fault is reasonable since the expression is a reference to the _data field, which is of derived type. However, being a select type selector, the selector must be a class with that declared type. Regtests fine. OK for mainline?
