[malisipi]

Describe the bug

ctx.create_image causes crash whole app while runtime.

Expected Behavior

ctx.create_image creates the image with clang like tcc/gcc.

Current Behavior

App is crashing at runtime. It's output of program.

C:\v-test> v -cc clang -skip-unused run app.v
Unhandled Exception 0xC0000005
print_backtrace_skipping_top_frames is not implemented
signal 11: segmentation fault
print_backtrace_skipping_top_frames is not implemented

Reproduction Steps

Put a random image file named v-logo.png in same directory with the code

import gg

struct App {
mut:
	gg &gg.Context = unsafe { nil }
}

fn main() {
	mut app := &App{
		gg: 0
	}
	app.gg = gg.new_context(
		frame_fn: frame
		user_data: app
	)
	app.gg.create_image("v-logo.png") // crash at the line
	app.gg.run()
}

fn frame(mut app App) {
	app.gg.begin()
	app.gg.end()
}

The line causes the crash: \- https://github.com/vlang/v/blob/master/vlib/gg/image.c.v#L50 \- https://github.com/vlang/v/blob/master/vlib/stbi/stbi.c.v#L120

Also fails stbi_test.v with Clang 15.0.6 on Windows 11 with V 0.3.3 522a9f5 . Test command: v -cc clang -skip-unused run stbi_test.v Output:

Same example works fine with Linux/clang & latest V. That means the bug could be located at Windows-specific code of C library.
