I get the following segfault with current gcc 4.3. This was introduced
between 20070330-r123378 (works) and 20070417-r123941 (segfault). This
is related to the use of anonymous namespace.
I believe it was caused by:
2007-04-16 Seongbae Park <seongbae.park@gmail.com>
PR c++/29365
* cp/decl2.c (constrain_class_visibility):
Do not warn about the use of anonymous namespace in the main input
file.

Please submit a full bug report,
Testcase:
