[Bug c++/43113] too long diagnostics in some cases of recursive template instantiation
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=43113 --- Comment #7 from Andrew Pinski --- For the original case in comment #0 we get in GCC 5+: : In instantiation of 'struct A::S>::S>::S>::S>': :5:11: recursively required from 'struct A::S>' :5:11: required from 'struct A' :8:12: required from here :5:11: fatal error: template instantiation depth exceeds maximum of 5 (use -ftemplate-depth= to increase the maximum) A < S > ht; ^

I came to a similar test-case, which is an invalid code. But maybe a different
kind of issue:
$ cat error-reduce.ii
template struct vec
{
static vec plus_negates struct repeat_factor;
vec < repeat_factor > repeat_factor_vec fini_reassoc (
{
plus_negates
$ gcc error-reduce.ii
...
error-reduce.ii:4:27: fatal error: template instantiation depth exceeds maximum
of 900 (use -ftemplate-depth= to increase the maximum)
vec < repeat_factor > repeat_factor_vec fini_reassoc (

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[...]AB::S[...]::S’ pr43113.C:7:11: recursively instantiated from ‘AAB::S’ pr43113.C:7:11: instantiated from ‘AB’ pr43113.C:10:20: instantiated from here pr43113.C:7:11: error: ‘AS::ht’ has incomplete type

We could avoid the two long lines by not printing the full instantiation, only the first recursion, that is, just 'struct AAB::S' -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43113
