Stack overflow in json parser when processing lots of "["

[schrewe]

Hello,
I used CI Fuzz to fuzz the pegtl json parser. I found a stack overflow in marke.hpp.
The bug is triggered by a input consisting of a large number of opening square brackets "[".
I don't understand the code well enough to see why this happens, but I hope the attached crash logs can help you.
If I can provide any further information or help feel free to ask.

Thank you for the report, but I already explained this when I was at your office (although I don't remember exactly whom I explained it to). The PEGTL allows you to write recursive descent parsers, so by default it is easy to trigger stack overflows. While other parser libraries take the approach to always limit the depth of the recursion, this has a runtime cost associated with it. This might not be necessary when you have trusted input or the input itself is reasonably limited (e.g. by it length). Following the C++ philosophy of "you don't pay for what you don't use", the PEGTL therefore relies on the user that is creating a parser to take care of detecting and limiting the recursion depth if necessary.

An example of how this can be done and what benefits it offers can be found in our JSON library taoJSON, not to be confused with the simple examples that we added to the PEGTL. There you will find that the parser does allow unbound recursion by default and you can add an optional limiter when needed, i.e. when parsing untrusted input. This is implemented in https://github.com/taocpp/json/blob/master/include/tao/json/events/limit_nesting_depth.hpp. The benefit of this approach is that in the context of a given grammar there are usually only very few rules that actually allow the recursion itself to happen. In the case of JSON, this is limited to arrays and objects - and as you can see in the above limiter, we only check the depth at those events. We therefore skip a lot of intermediate stack frames and a lot of intermediate code layers which makes the overall parsing more efficient.

That said, it might be beneficial to offer a more generic (but still optional) limiter that can be applied to any grammar. I'll see if I can come up with something, but even then this won't be a part of most examples by default.

Finally, the specific location of the stack overflow (match.hpp) probably doesn't matter much in this case. It will be any of the methods that participate in the recursion which spans quite a bit of code. (Plus the backtrace is incomplete)

I've added an (experimental) limiter, it's used in json_parse.cpp with a maximum depth of 42 (counting nested JSON values). Is that the example you were using?
