Originally reported on Google Code with ID 223

I'm using MacOS 10.7.5 and gcc 4.8.1, I compiled application with debug information
and no optimizations: -O0 -g3 -fsanitize=address -fno-omit-frame-pointer. When running
application I receive a correct error message (see output.txt) but without any debug
information. It is probably because on mac debug information is stored separately,
thus in case of valgrind one need to use dsymutil:
dsymutil <executable>
valgrind --dsymutil=yes
I could not find a similar option for AddressSanitizer.

Have you tried the asan_symbolize.py script or the ASAN_OPTIONS=symbolize=1 env var?

ASAN_OPTIONS=symbolize=1 is the default. It just wouldn't work w/o external symbolizer,
and there is none in gcc. So, I think the only option for now is to use asan_symbolize.py
script.

Please reopen if #2 doesn't help. 
Also please note, that gcc-asan on Mac is not something we actively support.
(gcc-asan on Linux is, and clang-asan on Mac&Linux even much so)

On my gcc 4.8 or 4.9 on linux I cannot find asan_symbolize.py.
However, if and only if I set "ASAN_OPTIONS=symbolize=1" and "export ASAN_SYMBOLIZER_PATH=/usr/bin/llvm-symbolizer-3.4",
then I get the symbolized report.

If I do "mybin 2>&1 | /usr/bin/asan_symbolize --demangle" (which is also from clang3.4),
I can see the symbols, but without colours and missing some info

> but without colours
asan_symbolize.py doesn't preserve the colors printed by ASan. Running "mybin 2>&1
| cat" will have the same effect.

> and missing some info
Perhaps it's using addr2line instead of llvm-symbolizer, try to set LLVM_SYMBOLIZER_PATH.

I made asan_symbolize.py accept ASAN_SYMBOLIZER_PATH as well as LLVM_SYMBOLIZER_PATH
in r193758.
