SYMPTOMS

A Virtual Device Driver (VxD) or driver built with Visual C++ fails to load or run.

Back to the top

The /ZI compiler option (debug info for Edit and Continue) uses the the compiler option /GF (constant string pooling) which places strings in .rdata. It is the presence of .rdata that causes the VxDs to fail. This option is turned on by default when a project is ported from Visual C++ version 5.0 to version 6.0.

RESOLUTION

Remove the /ZI compiler option or use /Zi instead.
