--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
The likely commit to introduce the ICE is r191412 in the 4.8 time frame:
r191412 | jason | 2012-09-17 23:47:35 -0400 (Mon, 17 Sep 2012) | 4 lines
PR c++/54575
* pt.c (instantiate_alias_template): New.
(tsubst): Use it.
(push_access_scope): Allow TYPE_DECL.
The last relevant one before that was r191400 which errors out with:
t.C:14:26: error: template instantiation depth exceeds maximum of 32 (use
-ftemplate-depth= to increase the maximum) substituting ‘template<class T, int
num> sp<T> rec() [with T = <missing>; int num = <missing>]’
return rec<T, num - 1>();
^
t.C:14:26: recursively required from ‘sp<T> rec() [with T = Base; int num =
0; sp<T> = A<Base>]’
t.C:14:26: required from ‘sp<T> rec() [with T = Base; int num = 1; sp<T> =
A<Base>]’
t.C:18:13: required from here
t.C:14:26: error: no matching function for call to ‘rec()’
t.C:14:26: note: candidate is:
t.C:12:3: note: template<class T, int num> sp<T> rec()
rec()
^
t.C:12:3: note: substitution of deduced template arguments resulted in errors
seen above
