Not really a review, just thought i'd mention this is also fixed by
the following patch
http://sourceware.org/ml/gdb-patches/2011-08/msg00235.html

this also fixes the original report of PR 10720 which seems to be a
dupe, not sure about the latter reports in 10720.
the test cases i added do not cover this either.

my guess is that deja-gnu doesn't meet this requirement to be able to
reproduce it.
