int main() { typedef int& T; T a = T(); }
Compiling the snippet above produces no diagnostic with gcc 4.4.0 20080701 or
gcc 4.1.2. However, reading n2691, 8.5 paragraph 6:
A program that calls for default-initialization or value-initialization of an
entity of reference type is ill-formed.
I'm pretty sure there's a similar statement in the current std.
Comeau seems to issue a diagnostic for the same snippet:
"ComeauTest.c", line 1: error: invalid type conversion
int main() { typedef int& T; T a = T(); }

------- Comment #4 from pinskia at gcc dot gnu dot org 2008-12-30 03:27 -------
The patch which fixed PR 21210 caused this regression. There needs to be an
extra check if we are moving away from using build_c_cast. In fact reverting
that patch fixes the issue and gets us back to where we were before for this
bug plus does not regress for the other bug. I think other patches fixed PR
21210 correctly.
Testing the reverting of the patch right now.

Reverting is a bad approach. We IMHO just want to check for
TREE_CODE (type) == REFERENCE_TYPE and issue diagnostics that references can't
be value-initialized.

Yes that seems like a better idea as we can give a better error message than
before.
