The Stackifier crashes on this testcase:

bool %T(double %X) {
  %V = seteq double %X, %X
  ret bool %V
}

------- Comment #1 From Chris Lattner 2004-06-10 23:27:06 -------

Fixed.  Patch here:
http://mail.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20040607/015168.html

As a bonus, the stackifier makes (a tiny bit) more sense now.

Testcase here: test/Regression/CodeGen/X86/2004-06-10-StackifierCrash.llx
