Subject: [Bug c++/13883] New: Assembler messages: symbol is already defined
X-Bugzilla-Reason: CC
X-SW-Source: 2004-01/txt/msg03382.txt.bz2
List-Id: <gcc-bugs.sourceware.org>

The following code:

struct A {};
struct B;
 
template < class TP > struct X : virtual A {
  template < class TP2 > X (TP2* ptr) {}
  template < class TP2 > X (const X <TP2>) {}
};
 
struct Y : X <B> {
  Y (A* a) : X<B>(a) {}
};
 
void func1 (X <B>);
 
void func2 () {
  A a;
  Y y(&a);
  func1(X< A >(&a));
}

produces these messages:

/tmp/ccdER9OM.s: Assembler messages:
/tmp/ccdER9OM.s:125: Error: symbol `_ZN1XI1BEC2I1AEEv' is already defined

on Linux x86, with G++-3.4 branch from a day or two ago.

I'm not sure if the "const X <TP2>" is well formed (it doesn't seem to work in
the non-template form), but the original code wasn't like that, that's a figment
of the automatic testcase reduction I did - so perhaps there's two bugs here.
