Requirements

The following are required for building this source code.

• GCC 4.9.3 or above

Building

Normal Build

/usr/local/gcc-4.9.3/bin/g++ -o MCTester -O -g -Wall main.cpp

ASAN Build

/usr/local/gcc-4.9.3/bin/g++ -o MCTester_ASAN -static-libstdc++ -static-libasan -O -g -fsanitize=address -fno-omit-frame-pointer -Wall main.cpp

Running

e.g. Run only Test 1;

Valgrind

/mnt/ValgrindInstallations/SuSE-11-SP3/valgrind-3.11.0/vg-in-place --tool=memcheck  MCTester 1 1

ASAN

MCTester_ASAN 1 1

Dr.Memory

/mnt/DrMemory-Linux-1.10.0-2/bin>./drmemory -light -- MCTester 1 1

Additional Settings

Run Time flags of ASAN

export ASAN_OPTIONS=detect_leaks=1:verbose=1

detect_leaks will enable LeakSanitizer (LSAN) with ASAN

Options to enable when running Valgrind

with --keep-stacktraces=none --undef-value-errors=no options to be inline with ASAN features

Options to enable when running Dr.Memory

-light : This will not detect uninitialized read and memory leak errors (to be inline with ASAN features)

-light -count_leaks : This will not detect uninitialized read errors, but lists leak errors.

Results

• Valgrind : Gist
• ASAN : Gist
• Dr.Memory : Gist

Major features

• Test suite can be run all tests e.g. MCTester_ASAN
• Test suite can run range of tests e.g. MCTester_ASAN 1 - 10
• Test suite can run tests starting from a test MCTester_ASAN 10 - this will execute all 10,11,12,....
• Test suite can run individual test e.g. MCTester_ASAN 1 1 - will execute only Test 1
