"POS data is invalid" error on Apple Silicon

[lrettig]

I've seen a few reports of this. It happened to me when I initialized using a Mac M2. Another user just reported to me:

I still fail to smesh using my Mac M2 book after syncing. If I use the postclit with cmd:
./postcli -verify -datadir ~/post/7c8cef2b -fraction 0.1
It complains:
POS data is invalid: invalid label in file 0 at offset 532096 {"module": "post::initialization", "file": "ffi/src/initialization.rs", "line": 238}

Here are a couple of reports on Discord, there may be others:
