System.AccessViolationException thrown by PrintDocument.Print when platform is X86

[gcaughey]

Description

PrintDocument.Print works fine for x86 builds with .NET 6.0.9 but throws exception in .NET 7 RC1. This only happens if the platform is x86.

Reproduction Steps

Create new WPF desktop application.

Change csproj so it looks like this:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>WinExe</OutputType>
    <TargetFramework>net7.0-windows</TargetFramework>
    <UseWPF>true</UseWPF>
	  <UseWindowsForms>true</UseWindowsForms>
	  <PlatformTarget>x86</PlatformTarget>
  </PropertyGroup>

</Project>

Add a button to MainWindow and change MainWindow.xaml.cs so it looks like this:

using System.Drawing;
using System.Drawing.Printing;
using System.Windows;


namespace TestPrintNet7
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        string text = "Hello world";
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            using (PrintDocument doc = new PrintDocument())
            {
                doc.PrinterSettings.PrinterName = "Microsoft Print to PDF";
                doc.PrintPage += new PrintPageEventHandler(doc_PrintPage);
                doc.Print();   // exception here!!!
                doc.PrintPage -= doc_PrintPage;
            }
        }
        void doc_PrintPage(object sender, PrintPageEventArgs e)
        {
            using (Font font = new Font("Consolas", 9, System.Drawing.FontStyle.Regular))
            {
                e.Graphics.DrawString(text, font, System.Drawing.Brushes.Black, 0, 0);
            }
        }
    }
}

Expected behavior

Text should be printed to file selected by Microsoft Print to PDF printer.

Actual behavior

Exception thrown on the line
doc.Print();

Regression?

Works fine in .NET 6.

Known Workarounds

none

Configuration

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>WinExe</OutputType>
    <TargetFramework>net7.0-windows</TargetFramework>
    <UseWPF>true</UseWPF>
	  <UseWindowsForms>true</UseWindowsForms>
	  <PlatformTarget>x86</PlatformTarget>
  </PropertyGroup>

</Project>

The problem only happens on .NET 7 with x86 platform target.

Tested on Windows build 25211.1001. The machine architecture is x64.

Looks like a bug in the LibraryImportGenerator refactoring. DOCINFO argument needs to be passed in as DOCINFO*.

@jkoritzinsky can you have a look as it seems caused by ccd67b0#diff-0004b77bd28bade5f8de26f55217352ec12d8af3c7de3d2c344f8e4ff8c38cebR51

Given we don't have 100% coverage of all of System.Drawing.Common I wonder if we should audit the generator conversion for other mistakes - or revert it for that assembly.
