> cc @pitrou @mapleFU in case you have any clue about why `parquet::arrow::SchemaManifest::decr::num_columns()` would sometimes return -1. Well, theoretically, `leaves_` could have more than 2**31 elements which, when casted to `int`, would result in a negative number. But of course that doesn't make sense in an unit test, and besides, it would certainly happen deterministically. So, the likely explanation is that the `leaves_` vector is corrupted. And that's quite plausible, given that `SchemaManifest::SchemaDescriptor` is a raw pointer. -- This is an automated message from the Apache Git Service.
