[odb-users] ODB crashes if callback function cannot be found

[Marcel Nehring]

Hello Boris,

I discovered a crash in the ODB compiler. If one specifies a callback function for an ODB object but forgets to declare this callback ODB crashes. It issues an error message about the missing callback, though. Example code and the corresponding output is attached below.

Regards,
                Marcel

#include <odb/callback.hxx>

#pragma db object callback(foobar)
class Object
{
public:
    #pragma db id
    int id_;
};

error: unable to resolve member function 'foobar' specified with '#pragma db callback' for class 'Object'
