Description

As shown in this paste,

http://paste.call-cc.org/paste?id=bfe5899d243035a1a5a67f48b97675dbc3405458

 $ cat foo.scm
 (use tcp srfi-18)
 (tcp-accept (tcp-listen 1230))
 $ csc foo.scm && ./foo &
 [1] 5449
 $ nc localhost 1230
 
 Error: segmentation violation
 
 	Call history:
 
 	foo.scm:2: tcp-listen	  
 	foo.scm:2: tcp-accept	  	<--
 [1]+  Exit 70                 ./foo

This works from csi -s foo.scm.

This is similar to #999, and actually caused by the fix for that ticket :)

A workaround for this problem (if it ever occurs in practice) is to add (use ports) to the program (or even (require-library ports) if you're paranoid about not importing anything you're not using).
