[cfe-dev] ASTImporter causes assertion in full mode

[Olaf Krzikalla]

Hi @clang,

the second assertion in DeclContext::addHiddenDecl fires, if I import a 
function in a namespace with two function paramters in ASTImporter's 
full mode.
I'm not that familiar with the ASTImporter but it seems, that the call 
to ImportDeclParts in ASTNodeImporter::VisitFunctionDecl imports all 
decls of the namespace including the currently processed function. Later 
on the function imports its parameters and there the assertion happens 
because the parameters are already imported.
Perhaps someone should look at this. I got it solved here by switching 
to minimal import.

Best regards
