Bug #: 55836
Summary: Weffc++: warning: base class 'class std::list<int,
std::allocator<int> >' has a non-virtual destructor
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++

When using -Weffc++ with this code
class Foo : public std::list<int> { };
the compiler warns that the base class "has a non-virtual destructor". While
this is true, there is not much one can do about it.
Suggestions: either remove the warning in these cases (when the problem is in
the standard library), or add virtual destructors to standard library classes.
If the compiler were to set a pre-processor variable when -Weffc++ is in
effect, adding virtual destructors could be made conditional.
