I can confirm this bug:
lakeview ok % cat foo.cc
class Class
{
public:
virtual ~Class();
virtual char const *what() const;
};
inline Class::~Class()
{}
int main()
{}
lakeview ok % g++-4.3 foo.cc
/tmp/ccsDsdCG.o:(.rodata._ZTV5Class[vtable for Class]+0x20): undefined
reference to `Class::what() const'
collect2: ld returned 1 exit status
lakeview no % g++-4.4 foo.cc
/tmp/cc0NApvV.o:(.rodata._ZTV5Class[vtable for Class]+0x20): undefined
reference to `Class::what() const'
collect2: ld returned 1 exit status
lakeview no % /usr/lib/gcc-snapshot/bin/g++ foo.cc
/tmp/cc6b2i3u.o:(.rodata._ZTV5Class[vtable for Class]+0x20): undefined
reference to `Class::what() const'
collect2: ld returned 1 exit status
All three work if I add "inline" to the declaration of the destructor.
