        @pricingDate Date,
        @last Date output,
        @prev Date output

No unknown should be 

01           flags
3d 00 00 00  usertype
3d           type

Usually under mssql bit 0 on status means nullable. It seems that in
some condition mssql return for nullable datetime using not nullable
type and nullable flag. As you can see parameter in input are passed
using not nullable type, perhaps this cause the problem.

Declaration of pdtGetDealRevalDates would help.
