Yes. > We only set __native_startup_state = __uninitialized; after calling > _execute_onexit_table(&atexit_table);, so while executing atexit_table, we > still have __native_startup_state as it was originally. > > // Martin I see. When thread which is executing atexit_table will somehow call _CRT_INIT(DLL_PROCESS_DETACH) then it would again execute atexit_table. So the above guard does not catch infinite loop when exit hooks calls again detach. _______________________________________________ Mingw-w64-public mailing list Mingw-w64-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mingw-w64-public
