Again, I will say that the problems with initdb are usually very
complicated to debug. It seems like you have gotten pretty far. For
me, it is just a challenge to get initdb running inside a debugger
because there is so much shell script startup before the postgres
process runs.

Take a look at utils/hash/hashfn.c:tag_hash. Is there a problem in that
code for your platform. Is the hash getting set, or is it falling
through the case statements? This code is clearly broken for
sizeof(int) > 4, but I think your ints are 4, and longs are 8. I bet
somewhere we are using a long where we should be using an int, and that
is why only your platform is seeing it. Is this true about long vs.
int. I can review our use of longs to see if there are problems.
