Have you verified that you can generate a core dump from a pure C program that simply dereferences a NULL pointer? I ask because a couple of years ago I was surprised that SIGSEGV did not result in a core dump on my macOS server despite having run "ulimit -c unlimited". I eventually traced it to the core dump directory not being writable by non-root users. Check the permissions which should look like this: > ls -ld /cores drwxrwxrwt 2 root wheel 64 Aug 10 11:21 /cores/ -- Kurtis Rader Caretaker of the exceptional canines Junior and Hank -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
