Wine crashes trying to run red_circle, something to do with not finding symbols
on the dlls

when building this project under msys2 windows
https://github.com/Kreijstal/glfw-example.git
and running it under wine, with the non windows dll dependencies copied over.
It turns it can't run under wine. It works fine under windows however.

On the off chance: does it work with WINEDLLOVERRIDES="libglesv2=d" ?

wine seems to have problems with that lib, though usually they don't result
with crashes, just black screens.

OK, that was a silly question: the example program explicitly uses GLES2.

Does 'module' debug channel offer more hints on why loading libGLESv2.dll fails
?

I am confused, what do you mean with debug channel?

Hello, I was able to install msys2, install needed packages inside msys2,
and clone glfw-example, built it and it showed not the crash from the comment
when run from the build tree inside the msys2 shell.

When I tried to run it from outside msys2 I needed to copy/link
the dynamic linked dlls to the directory where red_circle.exe is:
libgcc_s_seh-1.dll, libstdc++-6.dll, libEGL.dll, glfw3.dll, libwinpthread-1.dll

Then I received a similar "failed to load library" followed by a similar
crash trying to execute at address 0.
But I got the message about a missing zlib1.dll.

When I also link this into the directory of red_circle.exe I got no
longer a crash and the window shows up.

Can you retry when you copy zlib1.dll too?
(And if they are missing also the *.glsl files.)
