Please forgive me for not being able to contribute to the solution to
this problem. 

Eli or Daneil, if either of you can decide which solution is correct,
I'll look into fixing the problem. It just so happens that this bug
doesn't really effect me in any way. I just happened to notice it when
trying to enumerate many of the possibilities in GDB/MI.

Would it be good if I entered a bug report? or should i just forget
about this?
