Would you please tell me how to run the example?

I run the example with sbcl --script from terminal, I just get this error on Mac OS X:

2019-06-27 10:25:44.068 sbcl[55794:5419150] get 0x0

It seems related to the thread model as mentioned in issue, but i don't know how to fix it, Would you please tell me how to run the example?

After seversal days of googling, I found

(sb-int:set-floating-point-modes :traps nil)

could work around this issue.

@faywong, Thank you some much! I was having a similar issue with the updates I'm making to CL-Objc.
