Code: Select all

```
kingjames:CL_THEORY huterer$ ~/numeric/CAMB/camb my_params.ini
at z = 0.000 sigma8 (all matter) = 0.7930
at z = 0.000 sigma8^2_vd/sigma8 = 0.4066
Note: The following floating-point exceptions are signalling: IEEE_UNDERFLOW_FLAG
```

-fbacktrace -ffpe-trap=invalid,overflow,underflow,zero

(and a couple of others that don't make a difference). Once I do that + recompile, I get a slightly different error message:

Code: Select all

```
