That was easy:
-----------------
double bar(double);
void foo(double x)
{
double z,r,R,S;
r = bar(-0.5625) * bar(z*z+R/S);
}
-----------------
g/x> /home/bangerth/bin/gcc-3.5-pre/bin/c++ -O2 -c x.ii
x.ii: In function `void foo(double)':
x.ii:7: internal compiler error: in subst_stack_regs_pat, at reg-stack.c:1638

We can trigger the crash with only one variable:
==================================
int foo(double);
void bar()
{
double x;
foo(0)+foo(2*x+1);
}
==================================
