With this patch I'm still seeing odd trees in place_block_symbol(). In the
following, the type is the correct size (168 bytes), but the var_decl size too
small (48 bytes). place

Use .org instead of padding in section anchor block
This one ensures that offsets of emitted

No, of course that doesn't work. We make references into the section anchor
block as .LANCHORn+offset, so the items in the block must be exactly where
place_block_symbol() expect

There is a long standing bug with VLA types (see bug 28865) that has a similar
effect.

So the section anchor code places vars (and constants) in blocks according to
their alignment and sizes (varasm.c:place_block_symbol). The calculations are
all good, offsets are p

I believe this is triggered by powerpc turning on -fsection-anchors by default,

aligned if I compile with
