--- Comment #10 from Antony Polukhin <antoshkka at gmail dot com> --- Any progress? Multiple compilers already eliminate the atexit call. Moreover, some of the compilers even eliminate the guard variable after that https://godbolt.org/z/dbdfMrroa Note that the atexit elimination would benefit the libstdc++, as the latter now uses a bunch of constant_init instances that have empty destructor in libstdc++-v3/src/c++17/memory_resource.cc and libstdc++-v3/src/c++11/system_error.cc . It would be possible to eliminate the atexit calls for those cases and speedup startup times https://godbolt.org/z/MKaWKevzq
