Are core dumps the same as crash reports?

I'd been trying in my system (MacOS) to generate core dumps without much success, even following several guides in this site.

Here I created a simple sleep process and killed it to force a segmentation fault:

sleep 100 &
killall -SIGSEGV sleep

Output:

[1]  + segmentation fault  sleep 100

I do see when I go to Utilities->Console.app a Crash report, is this similar to a core dump (or if not in what ways are they different)?

Solution

  • Console.app shows you an Error Log by default. I believe you can also view Crash Reports by opening files with an '.ips' extension. A Core Dump is an object file that can be explored with a debugging tool such as valgrind or gdb.
