debuginfo::block() uses the provided trans::common::block for creating lexical block DIEs. trans::common::block, however, corresponds to LLVM basic blocks and not to rust lexical blocks.

A possible direction towards correcting this could be to look at the scope_info field in trans::common::block or to get ahold of the correct ast::blk somehow.

Nice find.

This turns out to be a false alarm. debuginfo::block_metadata() already searches for the right ast::blk. I added some documentation to make this clear to the currently open PR (#7710).
