[Bug c++/34950] [4.2/4.3 Regression] ICE in svn boost math toolkit

["rguenth at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #13 from rguenth at gcc dot gnu dot org  2008-02-12 23:13 -------
Ok, so based on comment #12 this is ice-on-valid-code, and that testcase
"works" for me with 4.0 and 4.1 which produce:

g++-4.1 -S t.ii
t.ii: In instantiation of ?A<T>?:
t.ii:12:   instantiated from ?S<T>?
t.ii:19:   instantiated from here
t.ii:7: error: no type named ?unnecessary? in ?T?

with 3.4 it ICEs with

g++-3.4 -S t.ii
t.ii: In instantiation of `A<T>':
t.ii:12:   instantiated from `S<T>'
t.ii:19:   instantiated from here
t.ii:7: internal compiler error: in lookup_member, at cp/search.c:1300
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
For Debian GNU/Linux specific bug reporting instructions,
see <URL:file:///usr/share/doc/gcc-3.4/README.Bugs>.

while 3.3 and 2.95 accept it.

No idea if we have a PR for 4.1 and the rejects-valid.  Janis, can you
hunt at where we started to go from the error with 4.1 to the ICE we now see?
