  {
    J a;
    J *b = 0;
    for (const int &c: src)
      b = b ? b->mutable_child () : &a;
    return a;
  }

Confirmed.  4.6 does not accept the testcase.

../../gcc47-g/gcc/cc1plus  -quiet t.ii -std=c++0x -O2
t.ii: In constructor 'M::M(const Container&)':
t.ii:36:1: error: PHI argument is not SSA_NAME, or invariant
PHI argument
retvalptr.4
for PHI node
b_10 = PHI <retvalptr.4(3), b_8(4)>
t.ii:36:1: internal compiler error: verify_ssa failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

this is inline transform going wrong.

Bisecting what fixed this would be nice.
