--- Comment #5 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
I don't want to mark it as a duplicate because PR16564 is a bit more complex.
I think this one should be easier to fix. We could always print:
pr43113.C:7:11: error: template instantiation depth exceeds maximum of 10 (use
-ftemplate-depth= to increase the maximum) instantiating ‘struct
A<[...]<A<B>::S>[...]>::S>’
pr43113.C:7:11: recursively instantiated from ‘A<A<B>::S>’
pr43113.C:7:11: instantiated from ‘A<B>’
pr43113.C:10:20: instantiated from here
pr43113.C:7:11: error: ‘A<S>::ht’ has incomplete type

--- Comment #7 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
For the original case in comment #0 we get in GCC 5+:
<source>: In instantiation of 'struct A<A<A<A<A<B>::S>::S>::S>::S>':
<source>:5:11: recursively required from 'struct A<A<B>::S>'
<source>:5:11: required from 'struct A<B>'
<source>:8:12: required from here
<source>:5:11: fatal error: template instantiation depth exceeds maximum of 5
(use -ftemplate-depth= to increase the maximum)
A < S > ht;

------- Comment #4 from manu at gcc dot gnu dot org 2010-04-28 08:46 -------
The output is now:
$ cc1plus pr43113.C -ftemplate-depth=10
pr43113.C:7:11: error: template instantiation depth exceeds maximum of 10 (use
-ftemplate-depth= to increase the maximum) instantiating ‘struct
A<A<A<A<A<A<A<A<A<A<A<B>::S>::S>::S>::S>::S>::S>::S>::S>::S>::S>’
pr43113.C:7:11: recursively instantiated from ‘A<A<B>::S>’
pr43113.C:7:11: instantiated from ‘A<B>’
pr43113.C:10:20: instantiated from here
pr43113.C:7:11: error: ‘A< <template-parameter-1-1> >::ht’ has incomplete type
pr43113.C:5:8: error: declaration of ‘struct
A<A<A<A<A<A<A<A<A<A<A<B>::S>::S>::S>::S>::S>::S>::S>::S>::S>::S>’
The template-parameter-1-1 is wrong, not sure what is going on there.
We could avoid the two long lines by not printing the full instantiation, only
the first recursion, that is, just 'struct A<A<B>::S>'

This is a different case than 9335.
Comeau does not handle this well either, so I am not sure how this case could
be solved.
