[Bug c++/28991] New: Static constructor emitted instead of initialized variable

[us15 at os dot inf dot tu-dresden dot de]

Instead of emitting an initialized variable in .data at compile time, gcc-4.2.0
emits a variable in .bss and a static constructor to initialize the variable at
run time. This is a regression from previous gcc versions.

Example code:

class T
{
    static void (*handler)();
    static void func() {};
};

void (*T::handler)() = func;

int main()
{
    T t;
    return 0;
}

gcc version 4.2.0 20060908 (experimental) emits:
08048416 t global constructors keyed to _ZN1T7handlerE
08049664 B T::handler

4.1.1 and 3.4.6 emit:
0804962c D T::handler
