Specify Symbol Path to asan_symbolize?

[nolo...@gmail.com]

Hi All,

I'm trying to run ASan on a project. During the self test phase, the project copies its binaries into a temporary directory and executes from that directory. This appears to cause problems for asan_symbolize.

Here's the recipe I've been using to invoke Asan:

export CC=/usr/local/bin/clang
export CXX=/usr/local/bin/clang++
export CFLAGS="-g3 -fsanitize=address -fsanitize=undefined"
export CXXFLAGS="-g3 -fsanitize=address -fsanitize=undefined -fno-sanitize=vptr"
./configure
make
make check 2>&1 | asan_symbolize.py

A typical output is below.

Any ideas how to help asan_symolize find the symbols needed for instrumentation?

Thanks in advance.

just replace the temporary path with the real path in the log, then
feed it to the symbolizer script.

Perfect, thanks. I did not realize it was that simple.
