H A Dtest_ubsan.c854686f4edf483db1e0d26d972bdb8fb65c8bfaa Tue Apr 10 18:32:58 CDT 2018 Jinbum Park <jinb.park7@gmail.com> lib: add testing module for UBSAN

This is a test module for UBSAN. It triggers all undefined behaviors
that linux supports now, and detect them.

All test-cases have passed by compiling with gcc-5.5.0.

If use gcc-4.9.x, misaligned, out-of-bounds, object-size-mismatch will not
be detected. Because gcc-4.9.x doesn't support them.
