This series of patches is aimed at removing pointer undefined behaviour
as per ISO C 1989/1999 sections 6.5.6 and 6.5.8, in dwarf.c. Most of
these are probably benign with current compilers, but I do worry about
some future crazy compiler optimisation making use of the UB to omit
some of the pointer bound checking.
