Bugzilla Bug 119753

I ran into the segfault described in the mailing list entry above. After erlang
compiled successfully it would never run, segfaulting every time. When I added
--disable-hipe to the configure script the segfaults stopped.

I don't know what specifically about my installation causes this, so here's my
emerge --info:

Hi Chris.

Thanks for a report and sorry about a delay - there isn't really any dev
specifically supporting erlang at the moment unfortunately (I am just trying to
keep an eye on "alternative development stuff" when I can spend some time away
from my "main" topics). 

1. What erlang version is this? Thanks for posting emerge --info, but could you
please be more specific about the erlang?

2. Do you still hit this, with few glibc updates happening since then? 

I added mkennedy and vapier to CC, as they seem to have been dealing with this
package the most lately.. 
Matthew, Mike: can you please add yourself to lang-misc herd, probably
specifying the <role> as well, so that you will see the bugs on erlang (as
bug-wranglers apparently simply assigned this to the first herd mentioned in
metadata)?

Downgrading the severity, since critical really is for system packaged and wide
and severe breakage..

George

I have the same problem, and I hope I can answer your questions:

1. I am running dev-lang/erlang-10.2.5 but I have also seen it with 10.2.10

2. It is still a problem for me. I am running sys-libs/glibc-2.3.5-r3  USE="nls
-build -erandom -glibc-compat20 -glibc-omitfp -hardened -linuxthreads-tls -nptl
-nptlonly -pic -profile -userlocales

I can also report that adding "--disable-hipe" to the ebuild seems to hide or
temporarily solve the problem
tux> diff /usr/portage/dev-lang/erlang/erlang-10.2.5.ebuild
/usr/local/portage/dev-lang/erlang/erlang-10.2.5.ebuild
46a47
>               --disable-hipe \

I have seen some indications that this problem is only reproducible on 2.4
kernels, but I am running 2.6.16
tux> uname -a
Linux tux 2.6.16-gentoo-r1 #3 SMP PREEMPT Mon Apr 10 20:17:38 CEST 2006 i686

Does this still exist with the current unstable?

This is fixed in dev-lang/erlang-11.2.1

all needed arches are stable now, I introduced a hipe USE flag in erlang 11.2.2
which enables hipe...if you do so, it may break -> no complaints to me.
