I’ve been wondering if there is any chance to use dtrace ustack helpers on Mac OS X for python and other interpreted languages? I know that you can figure out what python and php on OpenSolaris are doing when giving the ustack some extra memory for a buffer. Is this somehow possible on Mac OS X?

It looks like the ustack helpers are broken on MacOSX:

Edit: the opensolaris links have been decommissioned. Here’s another copy:

Edit 2: The best way (I know of) to change this is to escalate with your Apple developer liason (if you have one) or file a bug at bugreport.apple.com.
