OK, this is as small sas I can get it:
------------------------------------
template <typename> class X;

template<class T>
void foo() {
  const unsigned int j = T().begin()->first;
  X<int> v;
  v[j].push_back(0);
}
-------------------------------------
With tonight's compiler, I get
tmp/gg> ../build-gcc/gcc-install/bin/c++ -c x.cc
x.cc: In function `void foo()':
x.cc:7: internal compiler error: Segmentation fault
Please submit a full bug report,

Note that this happens during template parsing time, not during 
instantiation. I guess the code as is is illegal (since X is not
defined at the point of use, but the original code looked definitely
legal).
