MingHongDev

I fixed it myself. The problem my cause by the link error between g2o and CSparse. So, first install libsuitesparse-dev, then compile and make install g2o again.

I fixed this problem (double free or corruption) by myself. On CMakeLists.txt, ```cmake # set( CMAKE_CXX_FLAGS "-std=c++11 -Wall -O2 -march=native" ) set(CMAKE_CXX_FLAGS "-O3 -std=c++11") ```
