Never mind, -O0 -fpeephole2 makes it fail.

Reduced testcase for 4.0.x and above:
void s48_double_to_bignum(int exponent){
long length = exponent) + sizeof (long)) * 8) - 2) - 1)) /
(((sizeof (long)) * 8) - 2)));
}
This really should be filed

Here is the one for 3.3.3 and above:
typedef long bignum_digit_type;
void bignum_divide_unsigned_normalized( ){
bignum_digit_type guess;
guess = unsigned long) 1) << (((sizeof (bignum_digit_type)) * 8) - 2)) -
1)
