c++ - Game sometimes crashes when closing or process stay in memory -

my problem sometimes, when closing game, 1 of 2 may occur:

process stays in memory , have killed manually game crashes

i'm not sure if 2 related or independent issues. both of happen rarely, have eliminate these situations.

as crash, made dump , says crash occurs in peekmessage() function. code looks this:

bool running = true; /// reset timer timer.reset(); msg msg; zeromemory(&msg, sizeof(msg)); /// message pump while(running) { int msg_count = 10; while (peekmessage(&msg, null, 0, 0, pm_remove) && msg_count-->0) { ::translatemessage(&msg); ::dispatchmessage(&msg); if (msg.message == wm_quit) { running = false; break; } } if (applicationactive) { prepareframe(); renderframe(); } else sleep(1); sleep(1); }

from see it, message handling routine handling @ 10 messages per loop iteration. possible crash result of overflowing message queue? , process staying in memory result of "not reaching" quit message because it's far in queue? if helps, here's phone call stack dump:
