msys2 mingw32编译运行一切正常，mingw64能编译，但是运行examples.exe，报Segmentation fault的错误，大哥能不能修复下，64bit编译应该有问题

执行如下代码，当注释掉cg_move_to(ctx, 0, 0);时程序运行会崩溃
`static void crash_test(const char* filename)
{
struct cg_surface_t* surface = cg_surface_create(256, 256);
struct cg_ctx_t* ctx = cg_create(surface);

//cg_move_to(ctx, 0, 0);
cg_line_to(ctx, 256.0, 256.0);

cg_set_line_width(ctx, 10.0);
cg_stroke(ctx);

cg_surface_write_to_png(surface, filename);
cg_destroy(ctx);
cg_surface_destroy(surface);

}

tried to build on macOS on Ventura (13.6.1 (22G213))

$ gcc --version
Apple clang version 14.0.3 (clang-1403.0.22.14.1)
Target: x86_64-apple-darwin22.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

and get the error message:
error: aliases are not supported on darwin.
Same for clang.

I am confused with some of the syntax and wondered if you could help me out.

(I am new to this library and programming in c)

Here is my code

In the examples folder there is a file called main.c.

When using this library, that file conflicts with the main.c file used in the actual project.

To fix this I had to delete both the screenshots folder and the examples folder in the project.
