I always use strict, -w and fatalsToBrowser when developing,
but today this caused me a huge headache in
a simple script (with no syntax errors) that merely reads a
file, formats the contents, and displays the html.
It runs fine from the command line (with a few uninitialized value warnings) and could save the output with but it would just whirl and give no output via CGI. I found that the code looks and behaves perfectly via CGI unless both -w and fatalsToBrowser are enabled! Shut either one off (leaving the other on) and it works fine. I found a certain loop in the program that seems to cause this by throwing pairs of =cut around, but the loop seems mundane and similar to the others. Is this odd interplay between -w and fatalsToBrowser documented? Update: I said i'd node the entire script to craft in a day or two but am finding it difficult to abstract a simplified example. So i'll just suggest that if your error-free cgi script mysteriously hangs, turning off either -w or fatalsToBrowser may help. In reply to Re: use CGI or die;
