User Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:11.0) Gecko/20100101 Firefox/11.0
Build ID: 20120310010757
Steps to reproduce:
To try to better manage whitespace, I started coding such that the following pattern occurred a lot.
m/\s*></
I tried to view source in Firefox to review my code. I am using the Ubuntu 11.04 distro, but I also had a co-worker reproduce this on his Windows 7 machine with Firefox. It's also valid tag markup according to some XML documentation I read, though I don't know how directly XML tag markup is related to HTML tag markup.
The source:
<!DOCTYPE html>
<html
><head
><meta
http-equiv="Content-Type"
content="text/html; charset=utf-8"
/><script
></script
><script
></script
><script
></script
><script
></script
><title
>Firefox Fail Test</title
></head
><body
></body
></html>
Actual results:
Firefox crashed, although if I reduce the number of "/\s*></", the size off the text in the source view merely increases following.
Expected results:
Firefox should show my source code as-is and not crash.
