We cannot tell from the mere existence of a core file, why the core file was created.
You could load it in gdb, see what caused it to crash. This may be more puzzling than illuminating if it really did crash.
The core is probably a sparse file -- the same length as your computer's address space, but strewn with empty holes which cause the file's actual size on disk to be somewhat smaller. Check it with du.

core
CORE(5) BSD File Formats Manual CORE(5)NAME
core -- memory image file format
SYNOPSIS
#include <sys/param.h>
DESCRIPTION
A small number of signals which cause abnormal termination of a process also cause a record of the process's in-core state to be written to
disk for later examination by one of the available debuggers. (See sigaction(2).) This memory image is written to a file named by default
core.pid in the /cores directory; provided the terminated process had write permission in the directory, and the directory existed.
The maximum size of a core file is limited by setrlimit(2). Files which would be larger than the limit are not created.
The core file consists of the ~ Mach-O(5) header as described in the <mach-o/loader.h> file. The remainder of the core file consists of
various sections described in the Mach-O(5) header.
NOTE
Core dumps are disabled by default under Darwin/Mac OS X. To re-enable core dumps, a privlaged user must edit /etc/hostconfig to contain the
line:
COREDUMPS=-YES-
SEE ALSO gdb(1), setrlimit(2), sigaction(2), Mach-O(5), sysctl(8)HISTORY
A core file format appeared in Version 6 AT&T UNIX.
