Wow --- a core dump in pg_controldata is *really* unexpected, since it's
just printing some scalar fields. I can easily believe garbage out, but
a crash is harder. I'm beginning to think that there's something wrong
with your hand-rolled build, though I have no idea what.
Can you get a stack trace out of that? Should be enough to do
$ gdb path/to/pg_controldata
gdb> run /apps/database/postgresql-data
(wait for it to report segfault)

That doesn't seem to be your problem, at least not yet.
