Checking this on i686-unknown-linux-gnu, I find the same
result with flag_complex_method=2 as on ia-64. I am also
seeing the same result with logarithmic scaling (using frexp and
ldexp). Maybe I'm being bitten by the decimal fractions not being exactly
representable in binary, and the Lapack failure has some other reason.
I'll keep looking.
