interesting list, thanks.
Also, 700 entries is not a bad result considering the size
of the codebase and the age of parts of it (i am pretty sure
there is a lot of code 15+ years old which received little
if any mainteinance or use in the past decade).
(and i have nothing against old code except that compilers,
coding practices and the amount of peer review have improved
a lot over time, and so -- with some exceptions -- it is
easier to prevent some of these issues with more recent code).

cheers
