What is the most likely causes of signal 11, also know as "segmentation fault"?

14

Signal 11 (SIGSEGV, also known as segmentation violation) means that the program accessed a memory location that was not assigned to it.

That's usually a bug in a program. So if you're writing your own program, that's the most likely cause.

It can also commonly occur with some hardware malfunctions.

    This is such an informative answer, why would it get 4 negative votes? (the reason it's only -3 is because I just upvoted it). – user1271772 Jun 23 '19 at 22:24
