>Description:
g++ crashes on the following code

struct Base { virtual void f(); };
struct Wrong : public Base {};
struct Wrong : public Base {};

with the error message

bug.cpp:3: redefinition of `struct Wrong'
bug.cpp:2: previous definition of `struct Wrong'
bug.cpp:3: Internal compiler error in build_primary_vtable, at 
   cp/class.c:638
Please submit a full bug report, [etc.]

Just compile the code with "g++ -c".

The same code caused different problems with gcc 2.96,
see PR 1519.
