Bug #: 15464
Summary: Accessing anonymous unions from Python
Product: gdb
Version: unknown
Status: NEW
Severity: normal
Priority: P2
Component: python
AssignedTo: unassigned@sourceware.org
ReportedBy: andre.poenitz@digia.com
Classification: Unclassified
If I have a
struct X { union { Y y; Z z; } } x;
and later
a = gdb.parse_and_eval("x")
there seems to be no easy way to access the "union" "level".
'a' itself is the struct, 'a["y"]' transparently skips the union and gives the
named member.
It would be nice if there was a way to iterate through the children of the
struct. MI/varobjs nowaday seem to have that ability.

A good way would be to let the user use a gdb.Field
as the argument to [].
Iterating over the field values directly might be handy too.

I think this was fixed by the patch for bug #16113.

I can confirm that the union is now accessible using type.fields()[0] as index.
