2018年9月24日 · There are several possible causes for SIGILL (a totally random illegal instruction due to memory errors, a ud2 instruction intentionally inserted by the compiler, or a library function intentionally posting that signal), and it may be useful to …

Program received signal SIGILL, Illegal instruction. 0xb6fe8acc in ?? from /lib/ld-linux-armhf.so.3 It doesn't help to set the SIGILL handle to nostop (handle SIGILL nostop): Program received signal SIGILL, Illegal instruction. Program terminated with signal SIGILL, Illegal instruction. The program no longer exists. All backtrace I get is:

2016年11月20日 · SIGILL is the signal for an illegal instruction at the processor, which happens very rarely. The default action after receiving SIGILL is terminating the program and writing a core dump. The signal ID of SIGILL is 4. You encounter SIGILL very rarely, and I have absolutely no idea how to generate it in your code except via sudo kill -s 4 <pid ...

2018年12月3日 · It's not entirely accurate to say the schedule immediately stops giving the process CPU time. The kernel side of the signal handling is still executed by that process, but the process will only be executing kernel code so you are right when you say the program never receives the signal.

SIGILL for an illegal instruction (bad opcode); SIGFPE for a floating-point instruction with bad arguments (e.g. sqrt(-1)). A number of signals notify the target process that some system event has occured: SIGALRM notifies that a timer set by the process has expired. Timers can be set with alarm, setitimer and others.

2016年5月19日 · SIGILL, SIGFPE, SIGSEGV and SIGPIPE are signals related to program misbehaviour. Segmentation fault is probably the most recurrent situation, but in the end, all these cases can be treated as bugs, and I don't believe that catching the signal is the best way to recover from these situations.

2015年3月29日 · There is a valgrind bug Bug 322935 - disInstr(arm): unhandled instruction: 0xF1010200, valgrind: Unrecognised instruction on Raspbian explains that std::cout << std::endl raise a SIGILL. As the status is RESOLVED WONTFIX, I guess either I replace std::end with '\n' or I search an other way to debug.
