It's reported on receivers in extension function calls with stub type, as such calls can shadow members of finalized stub types causing change of resolve when corresponding type argument specified explicitly It works by checking extension receiver during call resolution parts run That way we can easily detect if we found an extension applicable to stub receiver and report call diagnostic for it KT-53739
