Emacs Crashes with "Memory Exhausted" Under ld-linux.so On Some Systems about portacle

[Shinmera]

What I've found so far is this: on some systems emacs simply crashes when launched under ld-linux.so, regardless of Portacle entirely. On my Arch systems I can reproduce this. On the Mint system I cannot.

The following mailing list thread hints that it might be a kernel related / deep emacs problem:

Thinking things through this seems even more suspect. Given that the whole thing works if ported from the Mint system to the Arch system I'm not sure if the above discussion applies to this, especially considering its age.

I suppose one thing that might be worth looking into is checking the values of ELF_ET_DYN_BASE on the respective systems, but I don't know how to go about that.

Here's the filed bug ticket on emacs: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=24708

It seems that on more recent Emacs versions (master, not yet 26.0) this problem has vanished. Since 26 doesn't have an rc yet and probably won't be released for some years I can't roll this out yet. Maybe the relevant changes will make their way into a 25.3 or similar in a more timely manner, though.

FWIW I patched emacs.sh to:

readonly TAG=emacs-26.0.91

but even after re-running emacs.sh, I still get 'memory exhausted' when starting portacle.

Interesting. I still wish I had any conclusive idea on why this happens, and especially why it only sometimes happens.

In all my tests 26.1 fixes this issue.
