cpuprofiler doesn't catch stack frames on linux with gcc 4.1.2/x86

[Google Code Exporter]

What steps will reproduce the problem?
1. configure && make on debian etch/x86 with gcc 4.1.2 installed
2. ./profiler1_unittest 1 1 a
3. ./src/pprof .libs/profiler a --dot

I was expecting something like this (both nodes and edges):
Removing 0xb7f2d50c from all stack traces.
digraph "./.libs/profiler1_unittest; 23 samples" {
node [width=0.375,height=0.25];

edges with <= 0 samples\l"];

}

But got this (only info about nodes):

N3 [label="_IO_str_overflow\n3 (13.0%)\r",shape=box,fontsize=26.1];
N4 [label="test_main_thread\n2 (8.7%)\r",shape=box,fontsize=22.7];
N5 [label="_IO_sgetn\n2 (8.7%)\r",shape=box,fontsize=22.7];

N7 [label="cuserid\n1 (4.3%)\r",shape=box,fontsize=18.4];
N8 [label="_init\n1 (4.3%)\r",shape=box,fontsize=18.4];
}

Tested on both gpt-1.2 and gpt-1.3
Patch attached.

Oops, it looks like my previous fix to work around __builtin_frame_address bugs 
was
incomplete, as you noticed.  I'll have this fixed for the next release.

This should be fixed in perftools 1.4, just released.
