Update for Erlang 18.2.1, the package builds and works at least for x86_64 and i686 (even the bug with erlang:processes() dumping core has been corrected by this). Below is the output from rpmlint, all the warnings have been present before, no new warnings or errors introduced:

--- Comment #19 from Peter Lemenkov lemenkov@gmail.com --- Ok, I've made a build for Rawhide. Unfortunately it's not that easy to upgrade Erlang in F22/F23 because this is a API/ABI-incompatible upgrade, and user has to rebuild all his/her NIFs and driver libraries.

--- Comment #27 from Filip Andres filip@andresovi.net --- My current hypotheses: * It's either a build problem or an upstream problem. * A build problem sounds a bit more probable to me as I would expect somebody else to hit the problem ahead of us. * If it's an upstream problem then I found the following:
As per ethr_atomics.c in the OTP source code there are two implementations of some functions -- one for architectures with native support, the other for architecture without it:
/* * This file maps native atomic implementations to ethread * API atomics. If no native atomic implementation * is available, a less efficient fallback is used instead. * The API consists of 32-bit size, word size (pointer size), * and double word size atomics. ...
Given the fact that packages built on my newish i7 processor work for me and packages built in koji don't, hypothesis is that there may be something fishy in the fallback branch of the code.
I've noticed that the build servers used by Koji use Atom processors (or at least the compiler for i686 builds is run with the -mtune=atom switch). Is it possible that the the processors lacks double word atomics, thus the fallback branch is run and there is an error there?
Is it possible to force a i686 build on a standard Intel processor not an Atom one?

I guess I may ask in the erlang-bugs mailing list but I would let it to you to decide if building for generic processor (instead of Atom) is a viable workaround or not.

I have built new packages using the following flags in the RPM spec:
%ifarch %{ix86} %global optflags -mtune=generic %endif

I've just rebuilt Erlang with -mtune=generic on ix86. However it didn't change anything on my machine.
Could you please test if it works for you or not? I'm talking about 18.2.2-3 version.
