Bug ID: 58545
           Summary: Wine preloader always crashes if I run under nix
                    develop shell, no programs work
           Product: Wine
           Version: 10.12
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown

wine64-preloader always crashes with "Segmentation fault" error at startup if
started under nix develop environment, which I created for developing
yabridge-based C++ app.

The command, nix develop, is a command of nix package manager. It automatically
download tools and libraries needed for developing my C++ app, and creates a
temporary shell with all required environment variables set for development. I
ran the command on NixOS 25.05.

If I understand correctly, nix develop command just sets environment variables.
I have no idea how that lead to a difficult to diagnose crash.

I attached the gdb debugger to debug wine64 and wine64-preloader. It seems that
it's crashing somewhere after wld_start, but I'm not sure exactly where the
issue is.

I uploaded the flake.nix for reproducing the issue to a GitHub repo.

I can't reproduce the issue by

* Sourcing environment variables dumped and running wine outside nix develop
shell.
* Setting really long environment variables and running wine outside nix
develop shell. wine can just handle it fine.
* Running wine inside nix develop, but with a different set of packages.

The issue is reproducible on wine built from current latest master commit
(https://gitlab.winehq.org/wine/wine/-/commit/5b5f7fa104582c08e860f84c6fb3619...).
