I thought the following message on the valgrind users list might be of
interest - it is in response to a message I posted. (The reply came
months after the original, so I didn't notice it immediately). I do not
know how to respond to the question at the end. The first patch at least
seems to have made it into the 2.4.1 release of valgrind.

Thanks for the report.

I"ve committed this to the valgrind 3.0 SVN repository.

How did you manage to get a scope at address zero? why do you think
such a scope should be ignored rather than added - maybe your program
really does have code at address zero?
