Hooked allocator frame not found, returning empty trace message is displayed in heapprofiler

[GoogleCodeExporter]

What steps will reproduce the problem?
1. i built gperf 2.0 in the cross compile environment for arm
2. there is no issue to use tcmalloc and cpu profiler
3. but, when i use heap profiler, there is an error like below
   "Hooked allocator frame not found, returning empty trace"

What is the expected output? What do you see instead?

<expected output>
Dumping heap profile to ./mybin.hprof.0161.heap (1 MB allocated cumulatively, 1 
MB currently in use)

<current output>
Hooked allocator frame not found, returning empty trace

i tried to use ./configure --enable-frame-pointers, but same error is happened 
again

What version of the product are you using? On what operating system?
O/S : linux 2.6.36
perf : 2.0

Please provide any additional information below.
- i used scratchbox2 to build tcmalloc for arm

I did almost exact the same thing you have done and got exact the same problem, 
but my OS is Linux 2.6.32.12-0.7 with  Intel X64, buiding with g++.

The function generating this message seems to have a comment regarding this 
issue. Refer to the comment at the end of the function 
MallocHook_GetCallerStackTrace in the file src/malloc_hook.cc. If that doesn't 
work then I would do the following:

1. Set a breakpoint in this function using gdb and generate a full backtrace.
2. Instrument this function to print out the backtrace as it is generating it.

From the results above we should be able to further determine where things are 
going wrong.

I found the same problem with GCC 4.7 on Fedora 17. I got it to work by 
manually editing the makefile to add -fno-omit-frame-pointers, as per revision 
150.

-fno-omit-frame-pointers is now explicitly specified for i386 as gcc changed 
the default to omit. Code is on the trunk at the present time waiting for 
release. Refer to issue-385.
