Confirmed. Fails everywhere.
The issue is that flag_complex_method is not the same in lto1 compared to cc1
so we lower the complex multiplication differently.
The specific issue is that we fold
D.2036_6 = __complex__ ( Inf, 0.0) * __complex__ (0.0, 1.0e+0);
D.2035_7 = D.2036_6 * D.2036_6;
to
D.2036_6 = COMPLEX_EXPR < Nan, Inf>;
D.2035_7 = COMPLEX_EXPR < Nan, Nan>;
with -fcx-fortran-rules (flag_complex_method == 1).
So the particular issue is a middle-end one while the general
flag_complex_method issue remains. In the end we need to move
flag_complex_method into the IL just like flag_wrapv.
I'm going to try fix the testcase at least.
