Hello,

please consider the attached example, where a chare A inherits from 2 others chare I1 & I2:

chare I1
{
entry void foo1();
};

chare I2
{
entry void foo2();
};

chare A : I1, I2
{
entry A();
};

When invoking foo2 on A, either foo2 of the class I2 is called (not A::foo2 !) if methods foo1 & foo2 are not virtual
or foo1 on A (vtable issue?) is invoked if they are virtual. Though class inheritance is not virtual, can it be the same issue?

Any help is welcome.

Christian
