--- Comment #10 from Iain Sandoe <iains at gcc dot gnu.org> ---
simplified C code reproduce (on 11.2 or 11.x up to r11-8936-gbe64e725111fdb=
9,
the following commit changes the optimisation of the loading and makes the =
bug
latent)

typedef int int32_t;

extern double floor( double );
extern double fabs( double );

static int32_t p10[] =3D {1, 10, 100, 1000, 10000};

int decimals(double n) {

    n =3D fabs(n);
    for (int ndigits=3D0; ndigits<=3D3; ndigits++) {
        double scaledN =3D n * p10[ndigits];
        if (scaledN =3D=3D floor(scaledN)) {
            return ndigits;
        }
    }
    return 0;
