ocaml-camlp4 doesn't build on ppc64/ppc64
/usr/bin/ocamlopt.opt -c -g -w a -I camlp4/import -warn-error A-3 -I camlp4/config -I camlp4/boot -o camlp4/boot/camlp4boot.cmx camlp4/boot/camlp4boot.ml

Error: Unbound module Camlp4
For more infos please take a look at http://ppc.koji.fedoraproject.org/kojifiles/work/tasks/3941/2443941/build.log
The actual error is:
Command got signal -10.
which is probably some kind of bus error (although 'man 7 signal'
says SIGUSR1 which is pretty weird).
Anyway, OCaml does generally work on ppc64 & ppc64le, and we even
maintain a special downstream backend for that. What hardware is this?
Also please enable core dumps and grab the stack trace.
Than, have you tried the build with a larger stack? We saw situations when the default was too low and "ulimit -s 65536" helped to workaround the issue.

Yup, that's actually quite likely to be the problem. If it
turns out to be this we'll have to modify the spec file.
Hi Dan, Richard
yes, with "ulimit -s 65536", ocaml-camlp4 built fine. We should add the workaround in spec file so that it build correctly on ppc in the future.
i have modified the spec file in my local branch and did scratch build. it built fine now
it's the patch for the spec file.
