--- Comment #13 from Tom Tromey <tromey at sourceware dot org> ---
Note with 1.12, the name referenced in comment #8 is

 <2><894>: Abbrev Number: 14 (DW_TAG_union_type)
    <895>   DW_AT_name        : (indirect string, offset: 0x1415):
NonZeroOptimized
    <899>   DW_AT_byte_size   : 24
 <3><89a>: Abbrev Number: 13 (DW_TAG_member)
    <89b>   DW_AT_name        : (indirect string, offset: 0x13eb):
RUST$ENCODED$ENUM$0$0$0$0$0$0$Empty
    <89f>   DW_AT_type        : <0x8a5>
    <8a3>   DW_AT_data_member_location: 0


... which is what I would expect, this is the "drill down"
situation I mentioned there.

So, I think your compiler just has a bug here.

I've fixed the other 1.12 regressions though.
Thank you for pointing this all out.
