 dwarf2 debug info


After talking with gdb folks and dwarf2 folks (who say this isn't the 
actual bug, there 
is some other gdb bug causing the crashes, because it doesn't depend on 
the end and base addresses being different), i'm going to close this as 
WONTFIX.
It's impossible for us to generate location lists with a end address > 
base address, and nothing with any brainpower would depend on it :)
