Hi,
this shows an optimization error with g77 -O on i686-pc-linux-gnu
(gcc-20001106):
REAL*8 VALUE(2), TOLD, BK
DATA VALUE /0D0, 1D0/
DATA TOLD /0D0/
DO I=1, 2
BK = VALUE(I)
IF(BK .GT. TOLD) GOTO 10
ENDDO
WRITE(*,*) 'Error: BK = ', BK
STOP
10 WRITE(*,*) 'No Error: BK = ', BK
END
g77 -o prog prog.f gives 'No Error: BK = 1.'
g77 -O -o prog prog.f gives 'Error: BK = 1.'
Bye, Martin.
