gcc LeakSanitizer doesn't work

Issue

This is with rhdevtoolset/3.0-rhel6 (i.e gcc4.9)

$ gcc -V
gcc version 4.9.1 20140922 (Red Hat 4.9.1-10) (GCC)

Problem: my simple program leaks memory. But
LeakSanitizer is silent.

Compile line:

g++ -fsanitize=address -static-libasan -g -o zzz zzz.C

When I run zzz, nothing gets printed.

Here is what should get printed:
