--- Comment #8 from Tom de Vries <vries at gcc dot gnu.org> ---
So, we're allocating type length for:
...
(gdb) up
#9  allocate_value_contents(value*) [clone .part.0] [clone .lto_priv.0]
(val=3D0xaaaaabdc46f0)
    at ../../gdb/value.c:1022
1022            ((gdb_byte *) xzalloc (TYPE_LENGTH (val->enclosing_type)));
...
which is type:
...
