Automate gdb: show backtrace at every call to function puts

Question

I want to debug some program. I need backtraces from all calls to some function, e.g. puts.

Now I use such gdb script:

set width 0
set h         


        

Answer 1

Try this instead:

set width 0
set height 0
set verbose off
start  # runs to main, so shared libraries are loaded
       # after you reach main, GDB should have libc symbols, "puts" among them
break puts
commands 1
backtrace
continue
end

If this doesn't work, please state operating system version.

EDIT: as osgx correctly points out, the other alternative is to add

set breakpoint pending on

before break puts
