Decided to relive some of my youth with a big of BASIC. Quickly found a crasher. Here's a repo:

  basica
  call me

(That is, from DOS start basica.exe then in the repl do "call me".) This gives the popup:

  'Undefined opcode 0xC7 at 0x00012EC8'

0xC7 is "mov r/m16, imm16" and definitely exists on the 8088.
