pprof produces messages: Use of uninitialized value $pcstr in hash element ... #252

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The following messages are printed under certain conditions by pprof from 
perftools 1.5:
Use of uninitialized value $pcstr in hash element at /usr/local/bin/pprof line 
3724, <SYMBOLS> line 30.
Use of uninitialized value $pcstr in hash element at /usr/local/bin/pprof line 
3727, <SYMBOLS> line 30.

They correspond to lines:
    my $sym = $symbols->{$pcstr};
    if (!defined($sym)) {
      $sym = [];
      $symbols->{$pcstr} = $sym;
    }

In my experience, I only see warning messages like that when there's some other 
problem reported, earlier by pprof.

Please list the full pprof output, along with the commandline you ran.  What 
version of perftools are you using?  On what O/S?  If you can attach the heap 
file and the executable that you ran pprof with, that would be helpful as well.
