Prerequisites
ImageSharp version
3.1.5
Other ImageSharp packages and versions
none
Environment (Operating system, version and so on)
Windows 11 23H2 22631.3880
.NET Framework version
.NET SDK 8.0
Description
This happens when using WrapMemory<TPixel>(void* pointer, int bufferSizeInBytes, int width, int height) and passing buffer that is too small for given width, height and TPixel even with correct bufferSizeInBytes value
Expected behaviour
Exception saying that given buffer is too small for given image size and pixel format
Actual behaviour
Fatal error. Internal CLR error
Steps to Reproduce
Run this code
using SixLabors.ImageSharp;
using SixLabors.ImageSharp.PixelFormats;
using System.Runtime.InteropServices;
unsafe
{
// these two lines are correct: no overflow ("checked") and no overrun ("bufferSize" is used)
int bufferSize = checked(8192 * 8192);
void* data = NativeMemory.Alloc(checked((nuint)bufferSize));
// passing correct buffer size
using Image<Rgba64> img = Image.WrapMemory<Rgba64>(data, bufferSize, 8192, 8192);
// oops!
img.SaveAsPng("output.png");
// already crashed at this point
NativeMemory.Free(data);
