We crash here

numbers

1145 gcc_assert (code == ARRAY_TYPE
1146 || VECTOR_TYPE_P (type)
1147 || code == RECORD_TYPE
1148 || code == UNION_TYPE
1149 || code == COMPLEX_TYPE);
because code == OPAQUE_TYPE.

I'll take a look at this. Probably missed something when adding OPAQUE_TYPE.

Aaron and I talked offline and I will actually be looking at this. I have it
recreated with a native build.

Since OPAQUE_TYPE is a type of aggregate, I modified the assert to allow code
== OPAQUE_TYPE and that fixes the ICE. I don't feel comfortable sprinkling
other OPAQUE_TYPE usage around anywhere else unless we have a test case that
shows we need it.

c++: Treat OPAQUE_TYPE types as an aggregate type [PR97947]
MODE_OPAQUE and the associated OPAQUE_TYPE were added to stop the
optimizers
from knowing how the bits in a variable with an opaque type are laid out.
This makes them a kind of pseudo aggregate type and we need to treat them
as such when we process the INIT initializer for variables with an
opaque type.
