My recent patch that introduced push_using_decl_bindings didn't
|
||||||
|
handle USING_DECL redeclaration, therefore things broke. This
|
||||||
|
patch amends that. Note that I don't know if the other parts of
|
||||||
|
finish_nonmember_using_decl are needed (e.g. the binding->type
|
||||||
|
setting) -- I couldn't trigger it by any of my hand-made testcases.
|
||||||
|
|
||||||
|
Sorry for not thinking harder about redeclarations in the original
|
||||||
|
patch :(.
