Fix mem_tracker-test failures on clang 3.7 -O3

clang 3.7 running with -O3 has an optimization that removes unused
memory allocations. One of the mem_tracker-tests relies on making such
an allocation to artificially increase the heap usage, so the test would
fail.

This adds a useless log message to log the allocated pointer, defeating
the optimization.
