# Test matrix:
# - Build matrix per compiler: C++11/C++14 + Debug/Release
# - Optionally: AddressSanitizer (ASAN)
# - Valgrind: all release builds are also tested with valgrind
# - clang 3.4, 3.5, 3.6, trunk
#   - Note: 3.4 and trunk are tested with/without ASAN,
#     the rest is only tested with ASAN=On.
# - gcc 4.9, 5.0
