Normally postgres is installed globally and you can only run one postgres server. This shows otherwise.

This script demonstrates how to:

• docs at https://code.google.com/p/address-sanitizer/w/list
• to be able to get asan working from node, both node.js and mapnik must be build with -fsanitize=address in CXXFLAGS and LDFLAGS. If this is not done you'll hit symbol errors on linux and on mac the program just quits silently
• to be able to get symbols with clang-3.5 + asan you need to use ./proj 2> log && asan_symbolize-3.5 / < log | c++filt
• asan seems to work on OS X (with source built clang++) but detects more problems (particularly leaks) on linux (with clang=3.5 from llvm apt packages).
• turn on everything except leaks export ASAN_OPTIONS=check_initialization_order=1:detect_leaks=0:strict_init_order=1:detect_stack_use_after_return=1:detect_odr_violation=0
• suppress node.js leaks with echo 'leak:node::Buffer' > supp.txt && export LSAN_OPTIONS=suppressions=supp.txt
