Confirmed. Here's something smaller: 
------------------------------ 
extern double log (double); 
 
void f(double x) 
{ 
    double g; 
    g = log(1.0 - x - 0.00001); 
} 
------------------------------- 
 
Compile with -ffast-math: 
tmp/g> ../build-gcc/gcc-install/bin/gcc -c -ffast-math vf_hqdn3d-snapshot.i 
vf_hqdn3d-snapshot.i: In function `f': 
 
vf_hqdn3d-snapshot.i:6: internal compiler error: tree check: expected integer_cst, have 
real_cst in tree_int_cst_lt, at tree.c:3220
