What do you mean by "fail at runtime"? Is there any error, backtrace, or something?
Here you go, it fails on both native windows x64 and wine
Unhandled exception: page fault on execute access to 0x0000000140000000 in 64-bit code (0x00000140000000).

System information:
Wine build: wine-9.0 (Ubuntu 9.0~repack-4build3)
Platform: x86_64 (guest: i386)
Version: Windows 10
Host system: Linux
Host version: 6.8.0-87-generic
How exactdo you compile? What is the cake invocation. And how is the environment?
I compile with clang-cl + lld-link and with msvc wine as sysroot, I also tried building natively with clang-cl and got the same error.
My cross toolchain uses rust and stdlib compiled from source, native builds use rust up binary toolchain
Only cl.exe builds succeed
We discussed this a while ago also in our chat: https://chat.slint.dev/public/pl/iqdf3z3xr3fppx1mmsjbarcawa
I could reproduce the issue, but I wasn't able to diagnose the root cause.
Oh wait, I remember now. I forgot to create an issue back then I think.
Currently it is enough that the issue is posted I guess, I think eventually some of the clients will want to build with clang-cl and this will get patched.
I'll stick to mingw till then.
