The parser will not recognize a nowiki block if it has a heading in it.

==Official Markup==
{{{ 
 Here is a summary of the official Creole 1.0 markup
 elements.  See http://www.wikicreole.org for the full
 details.

 Headings:
 =heading 1       ->    <h1>heading 1</h1>
 == heading 2      ->    <h2>heading 2</h2>
 ...
 ====== heading 6  ->    <h6>heading 6</h6>

 Paragraphs are separated by other blocks and blank lines.
 Inline markup can usually be combined, overlapped, etc.  List
 items and plugin text can span lines.
}}}

will result in http://www.wikicreole.org and =heading1 being parsed instead of {{{ }}}. If the headings are removed or escaped, the nowiki block is parsed.

This results in the tildes being printed which is what's supposed to happen. I've tried tracing the parsing using the puts statements in the code but I can't figure out what is actually happening.

It turns out this issue only appears when parsing strings with a different line ending than expected. This happens in a web environment.

Interesting. I see the fix in your repo, but it looks like you also need to commit the "nowiki_bug" test file.

Oops, sorry about that. Commited.
