------- Comment #1 from burnus at gcc dot gnu dot org 2007-02-06 16:52 -------
Confirmed. It crashes with -O but not without optimization.
Reduced test case:
Subroutine xcc_V_CONVERT(iepoch)
implicit none
logical :: IEPOCH
real :: XVECTOR(1:3)
real :: YVECTOR(1:3)
xvector = 0.0
if (iepoch) then
yvector(1:3)=xvector(1:3)
endif
end subroutine xcc_v_convert
