Full view of interface-wide types
For displaying the full view of a class-wide object, GDB relies on
the assumption that this view will have the same address as the
address of the object. In the case of simple inheritance, this
assumption is correct; the proper type is deduced by decoding
the tag of the object and converting the result to this full-view
type.
Consider for example an abstract class Shape, a child Circle
which implements an interface Drawable, and the corresponding
following objects:
Then the type specific data and the expanded name of the tag is read
from there:
(gdb) p my_shape'tag
$3 = (access ada.tags.dispatch_table) 0x8059ec4 (classes.circle)
To get the full view, the debugger converts to the corresponding type:
(gdb) p {classes.circle}0x8063e28
$4 = (center => (x => 1, y => 2), radius => 3)
Now, in the case of multiple inheritance, the assumption does not hold
anymore. The address that we have usually points to some
place lower. The offset to the original address is saved in the field
Offset_To_Top of the metadata that are above the tag, at address
obj'tag - 8. In the case of my_shape, this offset is 0:

Handle other cases than EVAL_NORMAL in the default case
In the evaluation of an expression in Ada mode, the default case
unwraps the argument unconditionally. For an object of a variant
record type, this unwrapping builds a fixed type from the
specification of the variant type and the actual values of the
object's discriminants. It means that unwrapping needs the "proper"
value for the object, not just a zero value with the proper type.
When not in EVAL_NORMAL, we cannot assume that the evaluation returns
such a proper value; it may well return a zero value of the
appropriate type e.g in EVAL_AVOID_SIDE_EFFECTS. It is wrong to try to
unwrap in that case.
In particular, a problem shows up when using expression of the form
{VARIANT_TYPE}OBJ. GDB first evaluates this expression in
EVAL_AVOID_SIDE_EFFECTS to compute the type, the evaluation of OBJ
in most cases returns a zero value of its type, and as UNOP_MEMVAL
is mapped to the default case its evaluation ends up trying to
read memory around address 0.
