--- Comment #12 from Pat Haugen <pthaugen at gcc dot gnu.org> ---
Just for completeness sake, this is what I whittled bifg21.f90 down to. r238496
produces a warning, r238497 does not. I'll also note 178.galgel also failed at
-O0, on powerpc64 at least.
Subroutine BifG21 (G21, W11, W20, V, U, NS)
Real*8, Dimension(1000,1000) :: HtTim
Integer N, K
Real*8, Allocatable, Dimension(:) :: POP2
Np = Max0(N,K)
Allocate( POP2(Np) )
POP2(1:N) = MATMUL( HtTim(1:K,1:K), POP2(1:K) )
Deallocate( POP2 )
Return
End
> gfortran -S -m64 junk.f90 -Warray-temporaries
junk.f90:10:23:
POP2(1:N) = MATMUL( HtTim(1:K,1:K), POP2(1:K) )
