            Bug ID: 18363
           Summary: source line echoing on "next" mysteriously turned off
           Product: gdb
           Version: 7.7
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: jason.vas.dias at gmail dot com
  Target Milestone: ---

With fully up-to-date Ubuntu 14.04.2 LTS @2015-05-01 's GDB 
7.7.1-0ubuntu5~14.04.2 , this sequence of input somehow turned
off echoing of input source lines, and I cannot understand why:

At this point, gdb is still echoing source lines with the 'n' / 'next' command: 
    (gdb) n
    233         if( i == Q_MSG_DURATION )
    (gdb) p (p - &buf[0])
    $20 = 140
    (gdb) p *((char[140]*)buf)
    $21 = "INSERT INTO quantiles VALUES( 1, 2, 0, 3, 2, 18, 419.362526251996 ,
15 , 1 , 469.946678558381 , 1 , 0 , 678.247236170935 , 7.73105044050213 "

But now it isn't - what did I do to turn it off ? Now only the source line
numbers are echoed on 'next' ( there were no intervening input lines between 
the last one shown above and this 'next'):

    (gdb) n
    290
    (gdb) 
    301
    (gdb) 
    293
    (gdb) n
    300
    (gdb) 
    293
    (gdb) 
    299
    (gdb) 
    293

I can't find any setting documented that turns echoing of source lines on or
off on 'next' .

I had previously done :
  (gdb) set print elements 0
to print whole arrays ( I now know I should have used 'set print null-stop
on').
But I can't understand how these settings would have effected source line
echoing or how a few print commands could turn off source line echoing .

Is there a setting that turns source line echoing on 'next' on or off that
I might have inadvertently set ?

Hi Jason,

A few questions.

1) Does this happen every time you issue the 'set print elements 0' command?

2) Also, what happens when you ask GDB to print the current region, using the
'list' command?

3) Do you have other commands in your $HOME/.gdbinit file?

4) Does this happen with every binary you try to debug?  Are they optimized? 
Do they have debuginfo?
