The mask is making the warning go away...but is it actually a fix?
This should be reported upstream. Would you be so kind to do that. If not, please at least add your scanelf log file so I can do the report.
Created attachment 174492 [details] /var/tmp/portage/dev-lang/erlang-12.2.5/temp/scanelf-execstack.log Scanelf log. I tried reporting the bug myself but I was told that OTP only has a private bugtracker. So maybe one should send a mail to erlang-bugs, but I'm not sure how upstream handles bug reports.

When I had a more reliable internet connection, I used to report all our patches to erlang-bugs mailing list...they reacted fast and in a friendly manner. Just try it. :)
Mail sent.
(In reply to comment #5) > Mail sent. Unluckily upstream does not react...we will wait until after the holidays.
This issue is caused by hand-written assembly code without a .note.GNU-stack section.
Created attachment 178130 [details, diff] Fixes the executable stacks on amd64 This patch can be easily extended to fix the other arches (arm, ppc, sparc, x86), too.

If you are afraid of it or don't have the time, I can do it, of course.
Done. http://www.erlang.org/pipermail/erlang-patches/2009-January/000362.html
And we got an answer: http://www.erlang.org/pipermail/erlang-patches/2009-January/000363.html Perfect. So we will wait for R13.

So we will wait for R13. > Could you do a revbump with upstream patch for exec stack issues? http://www.erlang.org/pipermail/erlang-patches/2009-February/000370.html And while at it, could you also include the following patch which fixes a segfault on amd64 with hipe? (suggested by upstream) http://www.erlang.org/pipermail/erlang-bugs/2009-January/001173.html Thanks.
Both fixes added. Closing. Please test and report back.
