If I understand you right, then you mean that the s_Memmap is not an "constexpr" array. As far as I understand this is not an issue that schould prevent compiling - I believe constexpr arrays are valid and different to const arrays? The former should not compile with this initializer. Also this variable is an linkervariable in my project, and I dont think gcc could "constexpr" it... even if I might be able to do away with the cast with something like extern "C" const unsigned _lnkDDRRAM[]; btw here is my error output for 4.7.2: nestedconstexpr.cpp:35:1: in constexpr expansion of ‘CNested(CAddress(1107296256u))’ nestedconstexpr.cpp:22:26: in constexpr expansion of ‘((CNested*)this)->CNested::m_PrimaryBlock.CAddress::CAddress((* & primary))’ nestedconstexpr.cpp:35:1: internal compiler error: in cxx_eval_indirect_ref, at cp/semantics.c:7435
