32-bit builds of Godot do not work with LLVM MinGW

[MBCX]

Tested versions

• Latest master (aa8d9b8)
• all versions after 4.4dev5

System information

Godot v4.3.rc (322e93592) - Windows 10.0.26100 - GLES3 (Compatibility) - Radeon RX 580 Series (Advanced Micro Devices, Inc.; 31.0.21921.1000) - Intel(R) Core(TM) i5-9600K CPU @ 3.70GHz (6 Threads)

Issue description

Any attempt at building Godot for 32-bit Windows will succeed, but then actually trying to run will crash with this

================================================================
CrashHandlerException: Program crashed with signal 11
Engine version: Godot Engine v4.4.dev.custom_build (55e55b4879f7ad89086aa26f2e53882cf85077f9)
Dumping the backtrace.
-- END OF BACKTRACE --
================================================================

And just stop. And for some bizarre reason, it does not crash if its a dev build with debug symbols? (dev_mode="yes" dev_build="yes")
I'm still not sure if this is a Godot issue or a compiler issue. This is a Godot issue, see next comment.

Steps to reproduce

1. Use the latest LLVM MinGW (can be older too, I tested 20231128
2. Compile for windows with arch="x86_32"
3. Wait for compilation and try to run the executable.
4. (extra) re-compile with dev_mode="yes" dev_build="yes" and see how it does not crash.

Did a git bisect, I confirm this is a Godot bug, and the culprit is #85167.

#99168 was merged yesterday and fixes some issues from #85167, could you check whether that fixes the 32-bit support too?

Built latest master (a372214) with LLVM 19.1.5, and it ran just fine!

RandomShaper thought ahead then 👌!

I'll do a production build (but with thin lto) to see if the issue is truly fixed.

[MBCX]

Yes! it built and ran, and here's the final proof!

So, I can close this issue then as a false alarm from my part.👍

Awesome, thanks for confirming the fix!
