[GCC] fully-qualified names in ASan reports

[ramosian-glider]

Originally reported on Google Code with ID 144

What steps will reproduce the problem?
1. Take example (using LLVM/Clang) provided in http://code.google.com/p/address-sanitizer/wiki/ExampleHeapOutOfBounds

2. I used:

    g++ -g3 -O0 -fsanitize=address -fno-omit-frame-pointer test.cc

I also tried different -g levels, -O levels and dropping "-fno-omit-frame-pointer".

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

All stack traces contains binaries+offset, but do not provide fully-qualified names
like in the example with LLVM/Clang. Is there a way to get more human-friendly output
with GNU GCC, .i.e., as in the example with LLVM/Clang? Or am I forced to use objdump
comparing ASM w/ source to locate the issue in the initial ASan implementation on GNU
GCC?

GNU GCC partial output:

Pipe the output of the command through asan_symbolize.py:

Thanks. It works as expected with asan_symbolize.py and c++filt, yet the script is not
included into GNU GCC (trunk).

Not that we are going to fully switch to llvm-symbolizer in near future.
We indeed need to do something in the gcc world (at least extend the documentation).
