The issue reproduces on Windows 7. It is easiest to reproduce with PageHeap enabled. In order to reproduce the problem with the provided samples, it might be necessary to use a custom program which displays images using GDI+, or any existing GDI+ client (such as Microsoft Office).

|
Attached is ane EMF file which triggers the crash.
