[PATCH] esx: Fix dynamic dispatch for types with more than one level of inheritance

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Traverse the whole inheritance hierarchy for dynamic dispatch as it is
already done for the dynamic cast.

Also make AnyType cast errors more verbose.

Reported by Ata Bohra.
