[Bug c++/39225] New: ICE if destructor doen't match class name

If the constructor of a class does not match the class name, the compiler dies
with a segfault.

I'll attach an example program.
running 

> g++ test.cc
test.cc:6: internal compiler error: Segmentation fault

will already trigger the bug.

The source code is not valid code, but with previous versions (e.g. 4.2) I got
a meaningful error message:

> g++-4.2 test.cc 
test.cc:6: error: expected class-name before ‘(’ token

Cheers
  Christian

------- Comment #2 from rguenth at gcc dot gnu dot org  2009-02-18 10:11 -------
It works for me with the release-checking built 4.3.3 release (as well as
4.3.0, 4.3.1 and 4.3.2).  With the branch r143959 and checking enabled it gives

test.cc:6: internal compiler error: tree check: expected class ‘type’, have
‘exceptional’ (identifier_node) in constructor_name_full, at
cp/name-lookup.c:1715
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

so I'm not sure if this is a regression.
