March 07, 2021 [Issue 21686] segfault if daemon thread is killed, interrupts syscall and throws exception | ||||

https://issues.dlang.org/show_bug.cgi?id=21686 --- Comment #1 from Tobias Pankrath <tobias@pankrath.net> --- adr says: so what i suspect it is doing is when the main function returns, druntime tries to do a final garbage collection sweep. part o tht GC sweep is sending SIGUSR1 to interrupt all threads [4:46 PM] the syscall then EINTRs. the thread is then put on hold until the GC is done. then it might be a race condition on the thread resuming and throwing the exception and the other thread deinitializing druntime [4:46 PM] just a guess but an educated guess at least -- |

Ruppe <destructionator@gmail.com> --- So you don't even need the throw to trigger the problem. void worker() { timespec s = timespec(time_t(10), 0); nanosleep(&s, null); asm { int 3; } } will random debug trap (the int 3 getting run), terminate cleanly (the thread must be stopped by the main thing), or segfault. -- |
