The leftmost number in <angle brackets> is the nesting level of that
die; so if the entry for the die after the first one you listed starts
with <2>, then it's a child of the <1> die. There should be
DW_TAG_member(?) dies.
(I'm apparently wrong about the DW_AT_name being mangled. Does the
DW_AT_containing_type attribute of the first die point at something
named "Soi"?)
