Stack overflow issue

[AdamKorcz]

While testing another library, I ran into a stack overflow in go-yaml. The impact of a stack overflow has already been discussed in https://github.com/goccy/go-yaml/issues/353.

Reproducer

Go version: go version go1.22.5 linux/amd64 Latest go-yaml commit: b2a8cc696a9efea74ec54695625870937ce24797
