Hi,
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.
/(merge.?using\s?()|execute\s*?immediate\s*["’`´\x2018\x2019])|(\W+\d*?\s*?having\s*?[^\s-])|(match\s*?[\w(),+-]+\s*?against\s*?()/
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?
Best,
Fahad Arshad
