I can confirm the issue on my 15-RELEASE VM : 

lldb mksh
(lldb) target create "mksh"
Current executable set to '/usr/local/bin/mksh' (x86_64).
(lldb) r
Process 21821 launched: '/usr/local/bin/mksh' (x86_64)
Process 21821 stopped
* thread #1, name = 'mksh', stop reason = signal SIGSEGV: address not mapped to
object (fault address: 0x62)
    frame #0: 0x0000000000231703 mksh`___lldb_unnamed_symbol426 + 355
mksh`___lldb_unnamed_symbol426:
->  0x231703 <+355>: cmpb   $0x0, (%rax)
    0x231706 <+358>: jne    0x2315d7       ; <+55>
    0x23170c <+364>: jmp    0x2315c0       ; <+32>
    0x231711 <+369>: movl   $0x0, 0x20ded(%rip)

Will look into it. Thank you for reporting this.
