--- Comment #16 from R. Diez <rdiezmail-gcc at yahoo dot de> --- I am slowly arriving at a different conclusion. "struct __cxa_eh_globals" has neither a constructor nor a destructor. Its members are pointers or integers, so GCC will not have automatically generated any constructor or destructor for this structure. Therefore, variable "static __cxa_eh_globals eh_globals" in the past was already initialised before any users (probably because static memory being zeroed on start-up). The situation has not changed now. This static variable already outlived anything else, as there was no destructor changing anything on termination. Your patch introduced wrapper "struct constant_init" around it, which makes GCC generate a constructor for the wrapper solely to register an empty destructor with atexit(). Otherwise, the wrapper does nothing else useful. Your patch also changes '__eh_globals_init::_M_init' (a different global object) to a static member. Is that not enough to fix the original problem?
