I tried this code:

fn main() {
    std::backtrace::Backtrace::force_capture();
}

running
cargo r --target i686-pc-windows-gnu

I expected to see this happen: Nothing

Instead, this happened:
wine: Unhandled page fault on read access to 726F735F at address 7AADD340 (thread 0734), starting debugger...

Running with
cargo r --target x86_64-pc-windows-gnu
using the 64bit target, no crash happens, as expected.

Would be helpful to get a backtrace of the crash.
@ChrisDenton maybe you have ideas

Please note that I got a crash from a different wine version (sorry, can't recall which one) as well.

@Bytekeeper The current Wine stable version is 9.0. Please try the latest stable Wine.

@Bytekeeper Also, it's not clear from your report that you actually have full 32-bit Windows support installed. It is not enough to simply have Wine installed to get that. You have to have a fully and correctly configured multilib setup. The Wine 9.0 release does significant work to reduce the need for that. Do other 32-bit Windows applications run on the system in question and successfully perform crash reporting with dbghelp?

Yes, I have a good setup - I run a lot of 32-bit applications (mostly Starcraft 1.16.1 and 32-bit applications connecting to it).
Here is an updated "program":

fn main() {
    println!("Yes, other 32-bit applications work");
    // std::backtrace::Backtrace::force_capture();
}

> file test.exe
test.exe: PE32 executable (console) Intel 80386, for MS Windows, 21 sections

> wine test.exe
Yes, other 32-bit applications work

This was with the same wine version, now let's retry with wine 9.0. I replaced the println with backtrace again:

> wine --version
wine-9.0
> wine test.exe
...
wine: Unhandled page fault on read access to 726F735F at address 7AAFD180 (thread 0024), starting debugger...

And the backtrace from winedbg:
