Segfault when running scripts/loadup-all.sh

[khinsen]

Describe the bug
I am trying to package Medley for Guix. So far I have packaged maiko with X11 support, which compiles without errors. Now I need to do the loadup step, which fails with exactly the same error messages as in #1045, i.e. a segfault after a couple of "Misaligned pointer in NativeAligned4FromLAddr".

To Reproduce
Steps to reproduce the behavior:

1. Run ./loadup (or ./scripts/loadup-all.sh

Expected behavior
Termination of loadup without any error message

Screenshots
No screenshot, the error messages arrive on the console:

$ guix shell --preserve='^DISPLAY$' -CN -L ~/src/guix-kh maiko coreutils grep which sed procps findutils util-linux -- ./scripts/loadup-all.sh

Context (please complete the following information):

• Are you using online.interlisp.org? no
• OS: Linux
• OS Version: Guix
• Display/window system: X11
• Host arch: x86_64
• Maiko version: 9343f58b17a26bc93fee5adf1254138a77ea890d
• IL:MAKESYSDATE: (I don't get to the point where I could do this.)

Additional context
I don't expect anyone other then me to solve this problem, as it requires my so-far unpublished Guix package for maiko. I am hoping to get advice on how to debug this issue. My Guix build of maiko does nothing unusual: it runs makeright x and copies the three binaries lde, ldeinit, and ldex into the right place for Guix.

[nbriggs]

That looks as though your ldeinit was not created with the correct compilation flags. You said you did makeright x, but you also need to do ./makeright init (in the maiko/bin directory) to (re)create ldeinit. ./makeright init clean will remove any leftovers before redoing the ./makeright init.

[nbriggs]

I verified that if you use lde in place of ldeinit the failure looks exactly as you reported.

[khinsen]

That was indeed my problem, thanks! I have submitted a pull request that adds a paragraph to the maiko build instructions to point out the particularities of ldeinit.

[nbriggs]

@khinsen - Thanks for the addition to the instructions. I'd like to understand where the problem ldeinit came from -- did we distribute it? or did you package up a copy of lde renamed as ldeinit because the documentation did not explain how to create ldeinit as required for running the medley loadup scripts?

[khinsen]

@nbriggs I went through the history of my Guix package, and quickly found the reason: I had at some point copied lde to ldeinit by mistake. Sorry for the false alarm! I have updated my addition to the build instructions accordingly.
