Hello, I also tried to compile using clang++
$ clang++ --version clang version 1.1 (Debian 2.7-3) Target: x86_64-pc-linux-gnu Thread model: posix $ CXX=clang++ make clang++ -c -o Application.o Application.cpp clang++ -c -o main.o main.cpp clang++ -o crash Application.o main.o clang++ -o crash-not main.o Application.o And I have the same behavior: crash in one case and no crash in the other.
