Static analysis flagged this. It's possible to segfault in the `*_tree_remove` function generated by `rb_gen`, as `nodep` may still be `NULL` after the initial for loop. I can confirm from reviewing the fleetwide coredump data that this was in fact being hit in production, primarily through `tctx_tree_remove`, and much more rarely through `gctx_tree_remove`.
