how properly use recursive

[sineptic]

When i run my parser(application). There is this error

thread 'main' panicked at /home/sineptic/.cargo/registry/src/index.crates.io-6f17d22bba15001f/stacker-0.1.15/src/lib.rs:197:21:
setting stack permissions failed with: Cannot allocate memory (os error 12)
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

and it freezes.

When I try to RUST_BACKTRACE=1 it run smth but, and print only memory allocation of {different count} bytes failed and then run, but don't print.

I can build without problem.
