            Bug ID: 16785
           Summary: internal error with "target record-full" followed by
                    "checkpoint"
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: patrick at parcs dot ath.cx

To reproduce:

$ gdb gdb
break main
run
target record-full
checkpoint

This sequence of commands results in the error "record_full_remove_breakpoint:
removing unknown breakpoint".

I can reproduce this error on gdb 7.6.2 and 7.7.50.20140331.
