If you're going to fix it, I'd go with my earlier suggestion:

  It'd be easily fixable by removing that terminator
  entry and using range-for in the other #if 0 block.

I.e., remote the -1 entry, and replace:

  for (i = 0; xlate[i].them != -1; i++)
    if (xlate[i].us == sig)
      {
	current_event.u.Exception.ExceptionRecord.ExceptionCode
	  = xlate[i].them;

with:

  for (const xlate_exception &x : xlate)
    if (x.us == sig)
      {
	current_event.u.Exception.ExceptionRecord.ExceptionCode
	  = x.them;
