--- Comment #1 from Tim Shen <timshen at gcc dot gnu.org> ---
This is actually the same as bug 61601. The crash is due to stack overflow,
because the implementation uses recursion.

If you set the stack limit to 100x higher (ulimit -s 819200 for me), it stops
crashing and have the somewhat expected quadratic behavior.
