No version information. Is this HEAD, with Jim's earlier DW_AT_ranges patch?
I don't think your understanding is correct, but you didn't show enough of the
DIE tree to be sure. Ignore inlined functions for a moment; let's just think
about functions and lexical blocks. A lexical block normally has a range of
associated PC addresses, and a function normally has a high and low pc. The
lexical block is a strict subset of the function, so it should be included in
the pc attributes of the function.
I'm guessing from your description that _S_get_pool is inlined into
get_allocator is inlined into main. Because _S_get_pool is inside of
get_allocator, it makes sense for its PC ranges to be a subset of those for
get_allocator. A PC always belongs to the innermost block.
