Iʼm on 10.14, and donʼt see this crash. Assuming my emacs-27 build is
similar to Justin's, itʼs this:

7988      setup_coding_system (coding_system, proc_decode_coding_system[inch]);
   0x000000010019645f <+143>:   mov    (%r12,%r15,8),%rsi
   0x0000000100196463 <+147>:   callq  0x10007b610 <setup_coding_system>

7989
7990      if (!proc_encode_coding_system[outch])
   0x0000000100196468 <+152>:   lea    0x4d3061(%rip),%r15        # 0x1006694d0
