I can reproduce the failure from CPAN RT#93159 by running
t/001_basic.t in a loop, and the failure is not surprising:
my $exponent = int rand 100;
my $q1manual = $q1;
for (1..($exponent-1)) { $q1manual =
Math::Quaternion::multiply($q1,$q1manual); }
'int rand 100' returns results between 0 and 99, and with 0 and 1,
the for loop is not run.
Ok, after applying the proposed patch from CPAN RT, I don't get this
problem anymore, and I now also get the failures we're seeing on
ci.d.n. But it takes quite some time to trigger them; possible
cuplrit in the code:
353: my $theta = rand(0.25*$pi);
which could be 0.
So far for today :)
Cheers,
gregor
