--- Comment #4 from Joost VandeVondele <Joost.VandeVondele at pci dot uzh.ch> 2011-04-04 10:50:57 UTC ---
reduced testcase .... aborts at -O1, goes fine at -O0. Thanks for implementing
the warning, without this, it would have been very difficult to find.

INTEGER FUNCTION S1(m,ma,lx)
INTEGER :: m,ma,lx

IF (((m < 0).AND.(MODULO(ABS(ma-lx),2) == 1)).OR.&
    ((m > 0).AND.(MODULO(ABS(ma-lx),2) == 0))) THEN
   S1=1
ELSE
   S1=0
ENDIF

END FUNCTION

INTEGER :: s1
IF (S1(1,2,1).NE.0) CALL ABORT()
END
