bug#24708: 25.1; Launching Emacs Under ld-linux.so Results in Memory Exh

From: Nicolas Hafner
Subject: bug#24708: 25.1; Launching Emacs Under ld-linux.so Results in Memory Exhausted on Some Linuxes

User-agent: Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Thunderbird/45.4.0

Attempting to run Emacs 25.1 with ld-linux.so under certain Linux
distributions will cause an immediate crash with a "Memory exhausted"
message. I can reproduce this consistently under Arch Linux (Kernel
4.8.1-1) and Debian Stretch (Kernel 4.6.0-1). However, Emacs launches
just fine with ld-linux under Linux Mint 17.1 (Kernel 3.13).

The command I'm using to run emacs like this is simply:
> /lib64/ld-linux-x86-64.so.2 /usr/bin/emacs

When running under GDB, the output is as follows:
> Starting program: /lib64/ld-linux-x86-64.so.2 /usr/bin/emacs
> [Thread debugging using libthread_db enabled]
> Using host libthread_db library "/usr/lib/libthread_db.so.1".

The only thing I've found related to this issue is a NEWS thread from
2005, though I am unsure as to how relevant this is for the current


The reason as to why I'm launching Emacs in this way is that I am
deploying cross-distribution portable packages of emacs that ship their
own versions of the shared libraries. In order for this to work I need
to ensure that the libraries are loaded from a custom folder, rather
than from the standard system directories. I need to invoke ld-linux.so
directly in order to do this.

Interestingly enough, if I build such a deployed package on the working
Linux Mint system --including all required shared libraries and
ld-linux.so in itself-- and copy it over to one of the other systems, it
launches just fine. Still, I would rather not have to potentially be
restricted to a build system that might break at any moment due to an
update to the Kernel or some other component that might trigger the bug.

If there's any other data that I could provide in order to help resolve
this issue, I would be more than happy to do what I can.

Sincerely, Nicolas Hafner
