--- Comment #1 from Dimitry Andric <dim@FreeBSD.org> ---
Similar to in bug 253881, somehow this works perfectly fine for me: 

(lldb) target create "./a.out"
Current executable set to '/share/dim/src/llvm/bugs/bug257829/a.out' (x86_64).
(lldb) r
Process 1220 launched: '/share/dim/src/llvm/bugs/bug257829/a.out' (x86_64)
This version of LLDB has no plugin for the mipsassem language. Inspection of
frame variables will be limited.
Process 1220 stopped

I think there must be something different in our environment(s) that causes the
error for you, and not me.
