64-bit app does not display undef runtime error

Following code (named myundef.for) contains an undefined INTEGER(7) variable and has been compiled/linked as a 32 and 64 bit binary using the /undef option. Executing the 32 bit binary results in a runtime error (as expected), however, executing the 64 bit binary does not!

      subroutine mysr(myhandle)
      INTEGER(7) myhandle
      INCLUDE <WINDOWS.INS>
      A=SETFOCUS(myhandle)
      end

      INTEGER(7) myhandle0
      call mysr(myhandle0)
      end

Code generation calls:

ftn95 myundef.for /undef /link
ftn95 myundef.for /undef /link /64
