Subject: [Bug c++/17620] New: [4.0 regression] Bogus error with duplicate base class breaks boost
X-Bugzilla-Reason: CC
X-SW-Source: 2004-09/txt/msg02610.txt.bz2
List-Id: <gcc-bugs.sourceware.org>

This is a recent regression that breaks compiling boost: 
------------------- 
template <bool> struct S {}; 
 
typedef S<false> B; 
 
struct D1 : B {}; 
struct D2 : B {}; 
-------------------- 
g/x> /home/bangerth/bin/gcc-4.0-pre/bin/c++ -c x.cc 
x.cc:6: error: duplicate base type `B' invalid 
 
Needless to say that the error message is completely bogus.
