[Openmcl-devel] openmcl unhandled exception

openmcl-devel,

Under 0.14.2-p1 I'm getting an "Unhandled exception 11" when trying to 
call an external program that reads from one stream and writes to 
another. I've tried to create a simple test case to reproduce my 
problem. It seems the problem occurs for me when the stream starts with 
an empty line. An example follows. Has anyone seen this kind of thing 
before?

Thanks,

Cyrus


(defun stream-test (sometext)
   (with-input-from-string
       (instr sometext)
     (let ((gstring (with-output-to-string
		     (gstream)
		     (run-program "cat"
				  (list)
				  :input instr
				  :output gstream))))
       (print gstring))))

(defun print-test (sometext)
   (print sometext))

(print-test "This is a test!")

(print-test "
This is a test!")

(stream-test "This is a test!")

(stream-test "this works
This is a test!")

(stream-test "
But this doesn't. This is a test!")


And the output:

? (load "pipetest.cl")
"This is a test!"
"

"This is a test!"
"this breaks
