Random text creates empty output

[markseuffert]

Hi,

I was testing latest Markdown library together with @wunderfeyd. With random text as input it happens sometimes that there's no output, just a newline. I tried to isolate the problem, but didn't find out that much. It happens in the Markdown Extra parser and around 14K of random input text.

use \Michelf\MarkdownExtra;
$my_html = MarkdownExtra::defaultTransform($my_text);

There was no problem with normal Markdown parser and regular text bigger than 14K.
Is there a way to get debugging output.... someone wants to have a look at our input files?

Here's a test file https://github.com/wunderfeyd/yellowcms-tests/blob/master/zzz-random2.txt

I used PHP 5.5 with
pcre.backtrack_limit => 1000000 => 1000000
pcre.recursion_limit => 100000 => 100000

This happens to me in v1.5.0 using PHP Markdown Extra with the following:

## Header {#my-header .my-class}

Removing #my-header or .my-class will correct this. Leaving them both together results in everything being eaten for some reason; i.e., I get back an empty string.

@jaswsinc Can you tell me more about your PHP configuration (version, and the pcre.backtrack_limit and pcre.recursion_limit settings)?

It works fine for me on the dingus.
