I seem to have a problem when running a program (using cl-opengl, cl-glut) under slime on the threaded version of sbcl for mac os.  Whenever I execute a compile/load file from slime,  slime disconnects from the process. The message is:<div>

<br></div><div>------</div><div><div>Lisp connection closed unexpectedly: connection broken by remote peer</div><div><br></div><div>Error during redisplay: (error Connection closed.)</div></div><div>------</div><div><br>
</div>
<div><br></div><div>However, when I run the lisp program from the repl in sbcl, it loads fine. </div><div><br></div><div> I seem to think it is a problem with cl-opengl.  when I evaluate this region in the file from slime (with as little as cl-opengl included in the list), it disconnects:</div>

<div><br></div><div><div>(eval-when (:compile-toplevel :load-toplevel :execute)</div><div>  (require :cl-opengl)</div><div>  (require :cl-glu)   </div><div>  (require :cl-glut)</div><div>  (require :cl-opencv))</div></div>

<div><br></div><div>However, when I evaluate other functions (that can be evaluated independently), it doesn&#39;t disconnect.  Also, running this code from the repl doesn&#39;t cause any problems - only from slime.</div>

<div><br></div><div>I am using the latest slime version as well as the macports of sbcl (threaded) which I dowloaded via:</div><div><br></div><div>sudo port install sbcl +threads</div><div><br></div><div>btw, NON-threaded is not a problem;  slime works fine with all the above code.</div>
