[Bug other/16051] New: Static libraries with global static initializer that have side-effect to main are removed at link

[nct at ysagoon dot com]

Static libraries with global static initializer that have side-effect to main 
are removed at link. Here is a simple example : 
You want to have a registrar in your main program that register classes in 
static libraries that are linked with it. In each static library, you have a 
global static instance of a class that register a class creator in the global 
registrar in its constructor. The linker completly removes the library code 
even if there is statics objects that have side effect in their constructors. 
 
I've created a very simple test case, it is available here :

Thanks,
