MoreOver, in both the failed and sucessful builds, ensureUpdated is > present in cppmodelmanager.o and that is linked into libCppTools.so. Before r214208 the body of "virtual QByteArray CppTools::Internal::CppModelManager::definedMacros()" (and the other two virtual functions) that call ensureUpdated() were removed: _ZN8CppTools8Internal15CppModelManager13definedMacrosEv/6495 (virtual QByteArray CppTools::Internal::CppModelManager::definedMacros()) @0x7f601c207520 Type: function Body removed by symtab_remove_unreachable_nodes Visibility: external public weak comdat comdat_group:_ZN8CppTools8Internal15CppModelManager13definedMacrosEv one_only virtual Now these virtual function bodies are kept: _ZN8CppTools8Internal15CppModelManager13definedMacrosEv/6495 (virtual QByteArray CppTools::Internal::CppModelManager::definedMacros()) @0x7f67c0347520 Type: function definition analyzed Visibility: externally_visible public weak comdat comdat_group:_ZN8CppTools8Internal15CppModelManager13definedMacrosEv one_only virtual previous sharing asm name: 12475 Address is taken.
