TAO_UIOP_Acceptor::open_default (see https://github.com/DOCGroup/ACE_TAO/blob/9ca0cfdade984635d126786b5496589741f50121/TAO/tao/Strategies/UIOP_Acceptor.cpp#L228) does use ACE_OS::tempnam, that will not work anymore when you disable tempnam, that code should be updated. A global search could show more places that need to be updated before we could disable ACE_OS::tempnam by default
