[Bug fortran/35724] New: Compile time segmentation fault for CSHIFT with negative third arg

["dick dot hendrickson at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The following program gives a compile time segmentation fault.
Changing the third argument to CSHIFT to either MF1 or -1 fixes 
the problem.

I didn't experiment with a unary minus expression for the 
second argument.

      SUBROUTINE RA0072(DDA,LDA,nf10,nf1,mf1,nf2)
! fails on Windows XP
! gcc version 4.4.0 20080312 (experimental) [trunk revision 133139]
!compile time seq fault

      REAL DDA(10,10)
      LOGICAL LDA(10,10)

      WHERE (LDA) DDA = CSHIFT(DDA,1,-MF1)  ! MF1 works, -1 works

      END SUBROUTINE
