compile trinitycore with -DASAN=1 -DCMAKE_BUILD_TYPE=RelWithDebInfo

Ensure that a directory called worldasan exists in the bin directory, where worldserver is:

cd <bin directory> eg: cd ~/wow/bin

mkdir -p worldasan

start core with:

ASAN_OPTIONS=halt_on_error=0:verbosity=1:log_path=worldasan/worldasan:detect_stack_use_after_return=1 LSAN_OPTIONS=verbosity=1:log_threads=1 ./worldserver

Test the result using ".debug asan memoryleak" and ".debug asan outofbounds" commands.

enjoy your valgrind like debug without slowing your server like hell.
