 tag causes no output,helenyhou,,"Posting this on behalf of Sirisian in IRC who sent the question to wp-hackers on my suggestion and didn't get anywhere.

I was writing an article on my blog with a huge code dump at the end inside of a pre tag. I noticed that this breaks wordpress. This is 100% reproducible by pasting http://pastebin.com/6m3RVGbr into a post then hitting preview (You can use blank pre tags. I just had stuff in them for a syntax highlighter plugin. It doesn't generate a page even with all plugins disabled anyway).

I believe it's caused because there's over 64 KB of data in the pre tags. Talking to someone in the IRC and they said:

> looks like there's a preg_replace_callback called clean_pre, probably that's what's failing due to size
> basically, probably wpautop()'s fault",defect (bug),closed,normal,3.4,Formatting,1.2,normal,fixed,has-patch,,
