scons: Allow building with Address Sanitizer.
libasan is never linked to shared objects (which doesn't go well with -z,defs). It must either be linked to the main executable, or (more practically for OpenGL drivers) be pre-loaded via LD_PRELOAD. Otherwise works. I didn't find anything with llvmpipe. I suspect the fact that the JIT compiled code isn't instrumented means there are lots of errors it can't catch. But for non-JIT drivers, the Address/Leak Sanitizers seem like a faster alternative to Valgrind. Usage (Ubuntu 15.10): scons asan=1 libgl-xlib export LD_LIBRARY_PATH=$PWD/build/linux-x86_64-debug/gallium/targets/libgl-xlib any-opengl-application Acked-by: Roland Scheidegger <>
