      Following the instructions here, I attempted to build the server with the address/leak sanitizers using gcc with the following invocation: 

      ./buildscripts/scons.py --modules= --dbg=off --opt=on --link-model=dynamic --variables-files=etc/scons/mongodbtoolchain_stable_gcc.vars --allocator=system --sanitize=address

      And got the following error from SCONS:

      Checking if C compiler supports -fsanitize=address... yes
KeyError: 'LLVM_SYMBOLIZER':
  File "/home/ubuntu/mongo/SConstruct", line 4544:
    env = doConfigure( env )
  File "/home/ubuntu/mongo/SConstruct", line 3618:
    if env['LLVM_SYMBOLIZER']:
  File "/home/ubuntu/mongo/src/third_party/scons-3.1.2/scons-local-3.1.2/SCons/Environment.py", line 405:
    return self._dict[key]

      This issue persisted after trying to set a shell env var for LLVM_SYMBOLIZER:

      export LLVM_SYMBOLIZER='/opt/mongodbtoolchain/v3/bin/llvm-symbolizer'

      Ultimately I got around this by building with ASAN using Clang (thanks acm!), using an identical SCONS invocation to the one above except with the Clang variables instead of the GCC ones. But there appears to be an issue with building with ASAN and gcc.
