[Openmcl-devel] Unprintable CCL::IMMEDIATE : #xEB

Yes, changing the :element-type in with-open-file from :default to  
'(unsigned-byte 8) makes the problem go away on both x86 and x86-64.  
So it looks like it is a combination of some sort of problem with the  
error reporting pathway and a creeping SBCL-ism that should be fixed.

thanks,

cyrus
