[erlang-bugs] Executable stack in beam.smp and beam

Hello everybody,

the package management system of the Linux distribution Gentoo - Portage
- has some QA mechanisms in place to verify a freshly compiled package
"behaves well". On of these mechanisms is the check for executable stack
with scanelf. While installing R12B I've stumbled upon executable stack
in the executables beamp.smp and beam. The scanelf log is attached, the
relevant Gentoo bug can be found at
https://bugs.gentoo.org/show_bug.cgi?id=249328

Thanks in advance,
Lars
