>From the reduced testcase in that PR, we get the following for the constructor (which is wrong):
{.bandD.636=2, .the_commandD.637=0, ._parentD.648={.bandD.640=2}, .tc_sccD.652=66}
The problem comes from:
gnu_type = make_node (possibly_overlapping_fields
? UNION_TYPE : RECORD_TYPE);
in decl.c:2627
Note that _parent overlaps with the stuff before it.
What needs to happen is we need to create a better type for this unless unions are aloud to have more
than one initializer.
It looks like we should be instead of using an UNION but access the type as a subfield (like the C++
front-end) and also when taking the address for the parent's type do:
"&a._parent".
This is a front-end bug. Fixing this one the way I recommend will also fix PR 19408 at the same time.
