thread 'main' has overflowed its stack

Step to reproduce

zola init test

then download https://gist.githubusercontent.com/CSUwangj/8ba2d160fcc080a9117761aa629d949c/raw/c38452fb393d89ea0d48af11ba7ca5930150cb39/test.md into content/test.md

then go to zola root and zola serve or zola build

[CSUwangj]

there is a very long line at rust code, I think it makes situation similar to #827

It builds fine my macbook :/ Can you try on 0.12?
Any chance you can dig into it? At least to know where the stack overflow is happening?

[CSUwangj]

absolutely yes, i'll try to find which thing cause stack overflow later

[Keats]

Thanks!

sorry for missing steps for reproducing, just change config.toml to build_search_index = true then you should trigger this problem.

and I believe errors occur at components/search/src/lib.rs:L99, where index is too deep to serialize. If you add a statement said println!("{:?}", index); before this line, you can get the log below:

now we could believe that there is too much depth in children to deal with.

I have no idea how to fix it in a short time, I think there might be some problems in the algorithm of building the search index?

[CSUwangj]

BTW there is same issue on 0.12

[Keats]

Oh that's interesting, I would have never guessed it came from there. Should we remove the tags from the search index?

[CSUwangj]

because I still not configure search in my blog, so I have no idea if we should remove the tags from the search index.

but I think that would be nice if put a FAQ or something similar to warn users.
