Yes, that's an existing soundness hole in the compiler. You won't accidentally code it up yourself though.

If the bar is "deliberately malicious code results in a segfault", get back to me when they fix

  memcpy(0x10000, 0x20000, 0x10);

EDIT: and even that's being charitable; the Rust issue is viewed as a compiler bug which should be fixed.
