 Hi.

 I've found out that the following shortcode breaks a page, it doesn't load
 or shows truncated:

 {{{
 [myshortcode arg1="Aenean consectetur ipsum ante, vel egestas enim
 tincidunt quis. Pellentesque vitae congue neque, vel mattis ante. In vitae
 tempus nunc. Etiam adipiscing enim sed condimentum ultrices. Aenean
 consectetur ipsum ante, vel egestas enim tincidunt qu. In vitae tempus
 nunc. In vitaentbnbsdgsdsdgsdhsdhdsdhdsh Aenean consectetur ipsum ante,
 vel egestas enim tincidunt quis. Pellentesque vitae congue neque, vel
 mattis ante. In vitae tempus nunc. Etiam adipiscing enim sed condimentum
 ultrices. Aenean consectetur ipsum ante, vel egestas enim tincidunt qu. In
 vitae tempus nunc. In vitaentbnbsdgsdsdgsdhsdhdsdhdsh" /]
 }}}

 I'm using XAMPP for Windows 1.8.1 ( php v5.4.7 ) and Twenty Fourteen
 theme.
 It doesn't seem to work in older versions of XAMPP either.

 If I truncate the shortcode, it starts working:

 {{{
 [myshortcode arg1="Aenean consectetur ipsum ante, vel egestas enim
 tincidunt quis. Pellentesque vitae congue neque, vel mattis ante. In vitae
 tempus nunc. Etiam adipiscing enim sed condimentum ultrices. Aenean
 consectetur ipsum ante, vel egestas enim tincidunt qu. In vitae tempus
 nunc. In vitaentbnbsdg" /]
 }}}

 I think the issue was introduced in
 https://core.trac.wordpress.org/changeset/28773, I tried to rollback to
 the previous commit ( 28772 ) and it worked.
