I’ve got this snippet below:

<snippet> <content><![CDATA[ ${1/^(\w)|(?: (\w))/(?1\l$1:)(?2_\l$2:)/g} ]]></content> <!-- Optional: Set a tabTrigger to define how to trigger the snippet --> <tabTrigger>jsvar</tabTrigger> <!-- Optional: Set a scope to limit where the snippet will trigger --> <scope>source.js</scope> <description>Javascript snake_case</description> </snippet>
Triggering the above snippet crashes ST3 build 3083 (portable version), results with the following dump file message:

A colleague of mine was able to replicate the crash with the above snippet. Am I doing something wrong with the snippet?

Yes, you can not apply a regular expression onto a field that has no value. And you can’t ask for an input value and apply a regular expression replacement onto it at the same time.

The crash is an unwanted side effect. github.com/SublimeTextIssues/Core/issues/58

Thanks for the response!

For this scenario, what would be a good workaround? I still want to create a simple snippet with regex substitution, but not have duplicates (as in the example in Sublime docs). I don’t think I can have a default and regex right?

Well, you could first type the content, then select it and bind a snippet that uses $TM_SELECTION to a keybinding. Other than that, I don’t really see an option because you can not instantly modify what you are typing (it conflicts with the WhatYouTypeIsWhatYouGet principle, if that exists).
