After you install security update 938464 in Windows XP, you experience slow performance and first chance exceptions in applications that use GDI+ to process GIF files

Support for Windows XP has ended

Microsoft ended support for Windows XP on April 8, 2014. This change has affected your software updates and security options. Learn what this means for you and how to stay protected.

Consider the following scenario:
  • You install security update 938464 (MS08-052) for Microsoft GDI+ on a computer that is running Windows XP.
  • You use a debugger or a runtime verification tool, such as AppSight, to test an application that uses Microsoft GDI+ to process Graphics Interchange Format (GIF) files.
In this scenario, the application responds slowly. Additionally, the debugger or the runtime verification tool report first chance exception errors.
The GIF codec in GDI+ 1.0 encodes GDI+ images that have 256 or fewer colors (8 bits per pixel). The GIF codec uses exception error information to decode GIF images. Therefore, you may experience access violations when you use a runtime verification tool to monitor a GDI+ program that uses the GIF codec.
Note Guard Page exception errors may still be reported after you apply this hotfix. To work around the issue, disable Guard Page exception catching in the debugger or in the runtime verification tool.
