#274 Instantiating object within class definition crashes

[Tim Tomkinson]

Demo script:

package require Itcl

itcl::class C {C #auto}

This crashes after displaying the following:

before Itcl_RegisterObjectVariable hPtr2 == NULL!

This is not a recent regression. Any guidance on what the right behavior ought to be?

(Yes, yes, I know it starts with "don't crash")

[Don Porter]

Well, this is a weird thing to do, I think. The demo script is creating a command [::itcl::parser::c0]. Hard to imagine that's ever the intent.

That said, it works in Itcl 3, and if we just revise the panic to a more forgiving reaction, it can work in Itcl 4 too it seems

[Don Porter]

Ok, check this out:

% package require Itcl
3.4
% itcl::class C { C ::x }
% itcl::delete object x
make: *** [shell] Segmentation fault

[Don Porter]

Fixed the problem with Itcl 3.

Then replaced the panic with acceptance.

Will have to see what new bugs this exposes.
