I'm sending this back to the maintainers list so others can comment. The
error in the rand I see in the log files is
error: assert (mean (x),a,0.03) expected
5
but got
5.0576
maximum absolute error 0.05761 exceeds tolerance 0.03
so it seems to me that this really is just a statistical glitch. Perhaps
Bill's idea of fixing the seed/state would address this.
As for the three errors in the sparse code, they are all
error: assert (bf .\ as,sparse (bf .\ af, true),100 * eps) expected
Inf + Infi 2 - 1i NaN - NaNi NaN - NaNi
0 + 0i NaN - NaNi NaN - NaNi Inf + Infi
0 + 0i 0 + 0i NaN - NaNi Inf - NaNi
but got
Inf + Infi 2 - 1i NaN - NaNi NaN - NaNi
0 + 0i NaN - NaNi NaN - NaNi Inf + Infi
0 + 0i 0 + 0i NaN - NaNi Inf - NaNi
Infs don't match
Looking at the above the Inf's do match. Probably the 4.1.x compiler is
using a difference representation of Inf in IEE754 for each of these
cases. So it seems to me that it is a gcc bug as it doesn't consistently
use the same Inf representation.
