[Bug fortran/17073] New: ICE with regmove

["lei at il dot ibm dot com" <gcc-bugzilla at gcc dot gnu dot org>]

This problem seems to be specific to ppc.  I was unable
to reproduce it on ia32.

% cat foo.f90 
SUBROUTINE SYSHTN 

PARAMETER (N=100) ! works if N=10
REAL*8, DIMENSION(N,N) ::  POP, POJ4
REAL*8 Y(N)

POJ4( M, 1:N) =  MATMUL( POP , Y )

END
