--- Comment #3 from Eugene Zhiganov <zed at lab127 dot karelia.ru> --- I have reorginized my data - now references to EventSource class and it's derivatives (timers, sockets, signals) are stored in explicitly named data members of other classes. That did not help, still crashes. Then I added destructor for EventSource class to see, if it is called or not. And it is... sample output of a program... ------------------------------------- 'RX-0 @ IDLE' got 'M1' from 'CLIENT-2' rx.RxSm.rxIdleM1 : fd = 12 'RX-0' registered 12 (esrc.Io) !!! esrc.EventSource.~this() : esrc.ClientSocket // call of the destructor !!! esrc.EventSource.~this() : esrc.Timer // call of the destructor 'RX-0 @ IDLE' got 'M0' from 'SELF' 'RX-0' enabled 12 (esrc.Io, oneshot) ecap.EventQueue.wait, n = 1, event @ 7FFE506B486C ecap.EventQueue.wait, n = 1, event @ 7FFE506B486C, event source @ 7FB726991F40 Segmentation fault (core dumped) ------------------------------------ So now I understand, why the crash is happening - an object reference, obtained from epoll_wait() is invalid, because the object was already removed by GC. But I do not understand, why GC destructs these objects...
