Sorry, I am not subscribed to the list so don't have the message to reply to for threading purposes, but attached please find a C reproducer that works on x86_64 but fails on i686. The particular issue seems to be the POSIX_SPAWN_RESETIDS flag - not setting that allows i686 to succeed too.
I don't have time to check this carefully, but it looks to me like the problem is that process_spawnattr calls setegid and seteuid instead of setegid32 and seteuid32. This causes truncation of the gid and uid.
