Package: g++-4.6
Version: 4.6.0-9
Severity: normal
Meanningless inline requests should be ignored by the compiler,
but this is not the case on armel (armv5tel), symbols disappear
instead.
class C {
public:
C();
private:
virtual void foo();
};
inline C::C() {
}
#ifdef inline_this_virtual
inline
#endif
void C::foo() {
}

Now, C::foo() is gone.
Note, that this subtlety is specific to the armel architecture only,
anywhere else C::foo() is not silently dropped.
