Hi @BrainyGenius,

I have .117 but cannot reproduce this.

Also, not sure I follow the repro steps since you can't actually change the expression while the debugger is on, nor can you start the debugger when there's errors in the regex, like the |+)? part where + is treated as match 1 or more of the previous token, but the previous token is also a metacharacter which means OR.

Would you mind double checking the steps?
