Correct, there is a size_t being passed as as an u64 as well.  That
explains why arm32 was broken too, and not just i386.  The quick fix is
to replace size_t with u_int64_t in sshbuf_get_passwd(), on line 513 of
sshbuf-getput-basic.c (with my previous patch applied).  I have a full
patch in the pipeline.
