问题
It looks that OS X (10.6) does not generates codedumps by default.
Using the ulimit -c unlimited is not a good solution because ulimit does set the limit in an environment variable. This will work only for console applications executed from the shell that executed ulimit. If you have a gui application this will not work.
回答1:
You can enable core dumps and then launch your GUI app from the command line using open.
$ ulimit -c unlimited
$ open /Applications/Address\ Book.app
I just looked at TN2124 and it suggests a similar approach, only without using open and just launching the app directly, e.g.
$ ulimit -c unlimited
$ /Applications/TextEdit.app/Contents/MacOS/TextEdit
