I tried to reproduce this and by accident i had a blocksize=4 in my
configure script, and i got immediately failed installcheck results.
They seem hash index related and can easily be reproduced:

SHOW block_size ;
 block_size 
────────────
 4096

CREATE TABLE foo(val text);
INSERT INTO foo VALUES('bernd');

CREATE INDEX ON foo USING hash(val);
ERROR:  index "foo_val_idx" contains corrupted page at block 0
HINT:  Please REINDEX it.

I have no idea wether this could be related, but i thought it won't
harm to share this here.
