cppducontext.cpp -> loc 227 ( if( !scopeContext ) )

that does not find the declaration. It tries to prepend ::test() afterwards 
(the function contexts' identifier) but that doesn't find anything either of 
course... It would need to be ::foo::bar ...

Anyways, this shows another strange behavior, apparently 

    DUChain::self()->removeDocumentChain(m_top.data());

doesn't work properly... I get lots of messages like these:

QDEBUG : TestDUChain::testLocalNamespaceAlias() 
kdevplatform(30334)/kdevplatform (language)?[0;31m 
KDevelop::TopDUContextDynamicData::load?[0m: Cannot open top-context for 
reading: "/home/milian/.kdevduchain/{a5f36799-30e3-4983-9b94-
e9aa54f3849d}/0/topcontexts/2" 

Maybe that's related?
