On Mac OS X, if I send SIGQUIT to my C program, it terminates, but there is no core dump file.
Do you have to manually enable core dumps on Mac OS X (how?), or are they written to somewhere else instead of the working directory?

A:
It seems they are suppressed by default. Running
$ ulimit -c unlimited
Will enable core dumps, and it will be placed in /cores/ as core.PID

A:
by default, specific directories in mac osx are hidden. you might want to enable this feature in the terminal and then the core dump should be visible within the directory /cores.

Thank you. I was browsing with Terminal (ls -lah), but that's a useful tip anyway.
