[Openmcl-devel] CCL/Cocoa Mountain Lion Challenges

A bit of a pattern is emerging:
- no obvious connection to version of CCL
- strong connection to version of OS X (Mountain Lion, 10.8.0 and 10.8.1 only)
- quite inconsistent
- can happen when making threads or not servicing events from main thread for some time
- more likely to crash on CCL 32 than CCL 64
- has a CPU and RealMemory surge manifestation (observe with Activity Monitor)
Here is a test case.
- Load code and eval (crash-me)
- observe CCL System memory in Activity Monitor
- keep pressing return to OK the modal dialog.
Things may be fine OR you get some initial hick up with some small CPU/RealMem surges making things slower and slower. In some cases RealMem will just use up all you have and crash CCL after growing to a couple of GB.
If you have a Mountain Lion machine please let me know if you also get problems with this.
