Initialize printed buffer

- var_decl: Declaring variable "tbuf" without initializer
- assign: Assigning: "target.base" = "tbuf", which points to
  uninitialized data
- assign: Assigning: "r.base" = "target.base", which points to
  uninitialized data

I expect it would correctly initialize length always. Add simple
initialization to silent coverity.
