Hello, I've been trying to solve problem in our application with loading PDF. Basically when i try to load attached PDF in my WPF application (either with pdfViewer.LoadDocument(byte[]) or PdfDocument.Load(byte[]) the program crashes with these errors in output log: The program '[39312] Program.exe: Program Trace' has exited with code 0 (0x0). The program '[39312] Program.exe' has exited with code -1073740791 (0xc0000409). This is only information I get when debugging, nothing else will pop up as an error. I have suspicion there might be some specific error in library, based on how debugging behaves in this scenario. This problem is only on 32-bit version of application, on 64-bit version it loads flawlessly. I would welcome any suggestion for solution and I will gladly respond to any questions regarding this problem. I wish you a nice day David S.

But you can ask the operating system to provide your application with up to 3Gb. To do this, add the following to your post build script.
editbin /largeaddressaware $(TargetPath)
The editbin tool comes with Visual Studio and can be found here
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29910\bin\Hostx86\x86\editbin.exe
The subject document allocates about 1.5Gb of memory, so with the LARGEADDRESSAWARE you will be able to open this document twice.
Pdfium itself does not handle out of memory situations, so you must catch such an exception yourself to avoid crashing the application and show an adequate error message to the user.
