[gecode-users] new IntArgs fails

[Christian Schulte]

Hi Denys,

Yep, it is! The reason is that argument arrays are much much bigger than one
would expect: they always include a static area for a small number of
elements (16) in order to avoid heap allocation for the most cases. So for
that reason, new is disabled so that people don't shot themselves in the
foot (we shoot them right away ;-) ). I think even MwG tries to stress that
point!

Argument arrays are really meant to just pass arguments, they are bad as
general data structures. Why not use vector instead?

Cheers
Christian

The following code does not compile:

    IntArgs* v = new IntArgs(5);

is that on purpose?

Cheers,
