This turns out to be an utterly weird .debug_loc reference into the TOC. I
think gcc var tracking had a seizure.
I cannot see why we would ever want a TOC reference in debug info, so I'm
closing this as wontfix. I suppose the linker could edit the DW_OP_addr <toc
entry>, DW_OP_deref to DW_OP_addr <what the toc entry pointed to>, DW_OP_nop,
but that's just silly when gcc shouldn't be generating this garbage in the
first place.
