Sorry about the delay in reporting -- it took me a while to narrow it to a specific commit -- but this PR breaks OIIO's CI, specifically when reading deep files through the core library. I get these messages:

EXR_ERR_BAD_CHUNK_LEADER Corrupt deep tile (0, 0), level (0, 0) (chunk 0): invalid packed data size 0
