No

Test case:

  1. Run any DOS debugger inside DOSBox.
  2. Assemble ud0 (or any other invalid instruction).
  3. Trace the instruction (DEBUG: enter T).
  4. The debugger now displays the first instruction of DOSBox's or its own interrupt 06h handler.

This simple patch fixes that. (Is the patch file in the right format?)

    Patch to disable tracing into exceptions

    It might be better to set the flag in CPU_Interrupt, although it's more important with exceptions.
