I did not configured CXX environment variable, so the codes were compiled using clang. Now, setting CXX=g++, I can successfully compile and link the codes. So the linking issue is only for clang.

I have attached a simple code, mps file and hot-start solution file to reproduce results. The code will read mps file and hot-start solution file and try solving the problem. However, the following three settings result in different behaviors:
>>> 1. CbcStrategyDefault strategy(0); // assertion fail
>>> 2. CbcStrategyDefault strategy(0, 5, 5); // infinite loop
