The current code dumps the memory between arg_start and arg_end,
which contains the argv pointers. This results in the
Core was generated by `<garbage>`
message when opening the core file in GDB. This is because the code is
supposed to dump the actual arg strings. Fix by using arg_strings and
env_strings instead of arg_start and arg_end.
