User space run-time memory error detection tools: Comparison

In this post, I will provide comparison on various memory tools I tried so far - Valgrind's memcheck, AddressSanitizer, MALLOC_CHECK_. The tests I tried on different tools is located at https://github.com/babuneelam/valgrind_tests/blob/master/vg_tests.c

Here is the comparison chart.

	Valgrind’s memcheck	ASAN	MALLOC_CHECK_
uninitialized use	✓
Read/Write after free	✓
buffer overrun	✓	✓	✓
Read/Write bad stack location (underrun)	✓
Memory Leak	✓
c++related test (ignore this)	✓
Overlapping memcpy	✓
double free	✓	✓	✓
Read/Write invalid stack location (overrun)	✓
Read/Write invalid global data location (overrun)
Performance hit	10-30x	?	?

Hope this helps.
