--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Keith Halligan from comment #0) > class MemAlloc { > public: > MemAlloc() {} > void* operator new[](size_t sz, const std::nothrow_t& nt) { > return ::operator new(sz, nt); > } Why is this function written as an overloaded operator new? You never use it for new-expressions like `new MemAlloc[n]` so why isn't it just a normal named member function that allocates memory? It isn't the cause of the bug, but it is confusing to have this extra operator new[] involved that is a red herring. It should probably be something like: struct MemAlloc { static void* alloc(size_t sz) { return ::operator new(sz, std::nothrow); } }; and then just call it as a normal static member function: void* operator new[](size_t sz, const std::nothrow_t&) { return MemAlloc::alloc(sz); }
