   I can reproduce it on bionic.  Here is what I have found so far:
   
   - It's only reproducible with bionic, I have both 19.04 (EOL) and 19.10 tested.
   - It's only reproducible with the tvm test, so normal training with XGBoost doesn't have
the issue.
   - It's only reproducible with pip installation.  Building from source works fine, which
is annoying.
   - From valgrind, it has 1 byte invalid read, which is not presented if built from source.
   - Valgrind also reported multiple invalid reads from tvm. (built from source without any
cmake flag).
   
   @hcho3  It would be of great help if I can obtain a debug build or `RelaseWithDebugInfo`
build.
