This change enforces the C++11 standard’s rule that deallocation functions without explicit exception specifiers are implicitly non-throwing. Previously, GCC only applied this implicitly to destructors. Now, operator delete and operator delete[], both global and class-member versions, will also be defaulted to noexcept. This change may affect name mangling for code that relies on precise exception specifications of these functions.
