[Bug lto/42009] LTO unable to link in presence of multiple inheritance

[wouter dot vermaelen at scarlet dot be]

------- Comment #2 from wouter dot vermaelen at scarlet dot be  2009-11-11 18:26 -------
I (independently) found the same issue today.

I managed to reduce it to the following testcase:

> cat foo.cc
struct Base1 { virtual ~Base1(); };
struct Base2 { virtual ~Base2(); };
struct Foo : Base1, Base2 { virtual ~Foo(); };
Base1::~Base1() {}
Base2::~Base2() {}
Foo::~Foo() {}
int main() { return 0; }

> g++ foo.cc
[works fine]

> g++ -flto foo.cc
/usr/bin/ld: /tmp/ccNr43fh.lto.o: in function
_ZTV3Foo:ccuOnB3i.o(.gnu.linkonce.r._ZTV3Foo+0x30): error: undefined reference
to '_ZThn8_N3FooD1Ev'
/usr/bin/ld: /tmp/ccNr43fh.lto.o: in function
