"Errors during preprocessing" are not equal to zero in perfmon ASP.NET counters

Question

When testing an ASP.NET application with perfmon, we find that the following field is nonzero:

ASP.NET Applications v2.0.50727> Errors During Preprocessing

The documentation says that this field is "Number of errors that occur during parsing, excluding compilation errors and runtime errors."

However, I was not able to find out why this is happening. Any tips on where these actual preprocessing errors are logged? Or how to enable logging so that we can fix these errors?
