[Bug other/27364] New: Gcc 4.2 miscompiles binutils

[hjl at lucon dot org]

Gcc 4.2 miscompiles binutils on Linux/x86 and Linux/x86-64. When gcc 4.2
is used, "make check" in binutils from CVS will have one failure in gas. The
problem is

     more_than_enough_bits_for_digits
        = (number_of_digits_to_use * 3321928 / 1000000 + 1);

around line 347 in gas/atof-generic.c is computed as 4 when -O2 is used.
