Your pattern has *E1, but you are hoping to match &E1. If you mean that E1 should be a random pointer-typed expression, then that constraint should go in the metavariable list, eg expression *E1; julia _______________________________________________ Cocci mailing list [email protected] https://systeme.lip6.fr/mailman/listinfo/cocci
