Address-Sanitizer Demo Project (Still In Progress)

This a quick example for how to use the address sanitizer to discover various programming errors in C and C++.

How is memory allocated?

What is a memory leak?

Building on OSX

On OSX, address-sanitizer currently requires a custom build of clang:

• See https://code.google.com/p/address-sanitizer/wiki/HowToBuild
• Add compiler-rt and libcxx to llvm's projects/ dir
• Run cmake with: CC=/your/custom/llvm-build/bin/clang CXX=/your-custom/llvm-build/bin/clang++ cmake ../src_dir/

Experimenting with the test project

This project includes a CMakeLists.txt file that should let you get started. Steps:

git clone https://github.com/Stanback/asan-demo.git
mkdir build
cmake ../asan-demo
make
./leak-demo
