> There is little point in upgrading to a package that is known to be
broken.
Agreed.
I don't think some of the people commenting on the ticket realise what
that warning is about. In fact, I personally feel gcc should consider that
an error and not just issue a warning. I doubt the Sun compiler would
permit that code.
> This particular bug does not appear to be present in cvxopt-0.9 (at
least I can't find the "incompatible pointer type" warnings in either my
own or boxen builds)
Me neither. That bug is a regression.
> so by upgrading, we would be introducing a regression into Sage.
Yes.
> I am very concerned at this "release it now, we'll make it work later"
mentality.
Me too. There is '''far''' too much emphasis in Sage of adding features
and far too little in controlling quality. This ticket seems to be a prime
example of that.
> If Sage is going to be a viable alternative to the M's, it needs to be
trustworthy -
Yes.
> complaints of "feature X is missing" are easily rectified, claims of
"Sage gave me wrong answers" can quickly turn into "you can't trust the
output from Sage" and are far more difficult to refute.
Yes. Likewise complaints of Sage crashed damages Sage's reputation. The
bug you found could certainly cause a crash.
