            Bug ID: 18112
           Summary: Search does not start at current line
           Product: gdb
           Version: 7.9
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: dpetras at gmx dot de

When a program is suspended at a breakpoint and I search for a regex, then the
search does not start at the current line, but at the beginning of the source
file. To reproduce, set a breakpoint in the middle of a function and run your
program until the breakpoint is hit. Then do a
(gdb) serach .
GDB should print the next line after the breakpoint hit. But instead it prints
the first line of the file with the breakpoint hit.

I assume this goes back the the introduction of function
clear_lines_listed_range(void) in file gdb-7.9/gdb/source.c

A fix could look like this:

--- source.c    2015-03-10 16:29:20.000000000 +0100
+++ .BACKUP/source.c~    2015-02-20 18:11:44.000000000 +0100
