gdt apply all function signature data types issue

[jmpews]

i had capture gdt from dwarf binary <A>.

<A> has a static c function with signature void init(int arg0, int arg1, int arg2, ing arg3)

<B> has a c++ function with signature XX::init(), so there is a symbol with name as init and namespace with XX

when click the gdt that capture with <A>, and all function signature data types to <B>, <B>'s c++ function XX::init signature was overwritten.

What was the signature source-type for function <B> prior to it getting applied? A function with a default signature source-type is generally allowed to be overwritten. We still have no-formal way of defining namespaces within an archive. It is unclear if we should limit this action to the global namespace. Hopefully @emteere can add his opinion.
