>Description:
I create a lib that contains some .cpp. One .cpp in the lib contains only a ctor that should register into an array.
If I launch the executable, the ctor is not called (not registered). If now, I call, in the main, a function of the .cpp, now the ctor is called.
The behavior semms to be: If there s a .cpp without any function call in a lib, then ctor are not called.
>How-To-Repeat:
tar zxvf staticclass.tgz
./go
./a.out
look that only 2 string are registered (bug)
emacs main.cpp
uncomment the test_function();
./go
./a.out
look that the 3 string are registered (ok)
