[gcc-4.3.1][c++] weird segfault with -O3 in constructor of a global object

[Maik Beckmann <beckmann dot maik at googlemail dot com>]

Hello,

This code
{{{
struct vector {
  vector() : x(0), y(0), z(0) { }  
  float x,y,z;
};

struct Foo { 
  int dummy; // commenting this out makes it run perfectly
  vector array_of_vectors[4];
};

Foo foo;

int main() { }
}}}
compiled with 
  g++ -O3 test.cpp -o test
segaults on my x86-64 linux box.

I compiled it with -g
  g++ -O3 -g test.cpp -o test
and gdb gave
{{{

}}}

Can anyone confirm this?

Thanks,
