Hello @FireBurn ,

Yes, those are known. They show up when running with the --enable-valgrind option.

[FireBurn]

So these aren't issues?

[martinhsv]

Closing as duplicate.

[FireBurn]

I don't think you answered my question, and which issue is this a duplicate off?

[martinhsv]

It is an issue. That is why it is explicitly called out in the code at ...

https://github.com/SpiderLabs/ModSecurity/blob/5dfc0a256a27ea6245a972a2a6ab9c1a4edd2599/src/parser/driver.h#L58

With the creation of your issue, it was the 6th one simultaneously open that fundamentally about the same thing. The oldest was #2502 .

I have since closed all of them and replaced them with a single new item (#2848 )

[FireBurn]

Thanks :D
