Unable to load a document - multiple floating point traps

[bhoman]

I have an executable which is a combination of both managed and unmanaged C++ with several sub-projects (dll's) that are C#. We are building in x86 mode using .Net 4.6.1. I used Nuget to install both PPdfiumViewer and PdfiumViewer.Native.x86.v8-xfa packages to one of the C# dll's. When I try to call PdfDocument.Load(file_and_path_name) I get an exception from Pdfium.dll. The exception is:

• Exception thrown at 0x172632F8 (pdfium.dll) in Traffic.exe: 0xC00002B5: Multiple floating point traps (parameters: 0x00000000, 0x00001121).
• Exception thrown: 'System.Runtime.InteropServices.SEHException' in PdfiumViewer.dll

I got the PdfiumViewer pdb files from the PDFiumViewer project and can drill down to the call to FPDF_AddRef(). It errors out at Imports.FPDF_AddRef() on line 25 in NativeMethods.Pdfium.cs.

I have my copy of PdfiumViewer in the same directory as the exe file and the Pdfium.dll in an x86 subdirectory. If I call LoadLibrary(pdfium_path), LoadLibrary appears to succeed.

I have both your Demo project and a separate stand alone WinForm project running correctly using the same files and formats, so I'm not sure what is different here.

Any suggestions or steps I could use to debug the problem?
