[Bro] Regular expression behavior

I am testing some regular expression in bro and Bro2.0 is giving me weird behavior. For example, the following regular expression puts Bro in an infinite loop.


Note that the \x2018 and \x2019 are ASCII codes for LEFT SINGLE QUOTATION MARK and RIGHT SINGLE QUOTATION MARK.

If I plug in the actual single quotation marks then I get a segmentation fault. 

Any idea what is going on?
