Using current SVN gcc/gfortran, the following program gives a SEGV with
gfortran -ftree-vectorize -O3 -c
but not if I remove the -ftree-vectorize option.
The vectorization of sqrt is PR21466 / PR30032, but afterwards it was still
working. Thus it is probably some interaction between the gimple work and the
sqrt vectorization.
------------------------------------------
SUBROUTINE EOS(NODES, DENS, PRES, CS, CGAMMA)
IMPLICIT NONE
INTEGER NODES
REAL CGAMMA
REAL, DIMENSION(NODES) :: DENS, PRES, CS
REAL, PARAMETER :: RGAS = 8.314
CS(:NODES) = SQRT(CGAMMA*PRES(:NODES)/DENS(:NODES))
END SUBROUTINE EOS

Hi Tobias,
could write this into a test case for gfortran.dg?
If it broke once, we should at make sure it doesn't break again.
