The following code snippet:

  #include <vector>
  struct A { std::vector<int> a;};
  template<class C> struct B  { C c[33]; };
  struct Boom { B<B<B<B<A> > > > s; };

seems to make GCC to allocate huge amounts of memory:

$ gcc x.cpp
virtual memory exhausted: Cannot allocate memory

(virtual memory is limited by ulimit to 1GB)

$ gcc --version
