Hi Paul,
code->expr1->symtree->n.sym->ts = code->expr2->ts;
+ /* Sometimes the selector expression is given the typespec of the

s/inappropraite/inappropriate/
+ if (code->expr2->ts.type == BT_DERIVED
otherwise it LGTM.
Thanks for the patch!

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?
