This is a list of known problems that are unlikly to be fixed.

- when opening or saving files the "save" or "open" button of the widget
  is sometimes the wrong one. doesn't affect program behaviour.
  if you find out how to fix this one, tell me please!
- when register values get too big in ramsim, ramsim segfaults.
  this is a bug in libQT QString function.
- Calls to free_parstree() in plic are commented out.
  if you comment them back in, the program will segfault
  on various things you try to compile.
