It might be missing some initialisation in the NetBSD implementation of 
Rust.  It's panicking in this function:

  https://doc.rust-lang.org/src/std/sys/unix/thread.rs.html#835-914

There's some OS-specific code for other BSDs.  Does NetBSD also need to 
do something specific here?

Or maybe you're just running out of stack space.
