[Ecls-list] Building a CGI program

[William Hounslow]

Hi

I have created a standalone executable containing the simplest possible 
CGI script:

(princ "Content-type: text/html")
(terpri)
(terpri)
(princ "Hello, World.")

When placed in the cgi-bin directory and invoked from the command line, 
it works perfectly. However from the browser I get a 500 error:

malformed header from script. Bad header=No restarts available.: testpage

I assume this is a Lisp initialization error message being interpreted 
as the program output. The Apache error log is no more informative.

Any ideas about what is causing this or how to trap it in order to see 
the full message?

Thanks

William
