>Description:
This example shows that the instaciation of static class members is not correctly handled depending on the link method. When using g++ to link the list of *.o's everything is correct. When linking with a library it is not. See example. Simply start compile.sh and watch the output.

1. The first version is the correct one. Right before main() the static member m_stClass of classA is constructed, which leads to the output   staticClass:::staticClass() called" before main(). Then main starts and everything is fine.

2. This version shows that the linker does not resolve static member dependencies within libraries. Obviously non-static components like the function int return_five() are handled correctly. The compiler bug is that the staticClass object, which is reqired by classA, is never instanciated.
>How-To-Repeat:
see attached zip-file und execute compile.sh
