     Type:  defect         |     Status:  new
 Priority:  normal         |  Milestone:  4.11.1
Component:  General        |    Version:  4.10
 Severity:  normal         |   Keywords:
---------------------------+--------------------
 Compiling dumpbuf.c causes the following warning to be issued multiple
 times:

 {{{
 warning: pointer targets in passing argument 1 of 'snprintf' differ in
 signedness [-Wpointer-sign]
 }}}

 This seems to happen because {{{line_buffer}}} is declared as
 {{{unsigned}}}.
