gfortran should not accept the following:
character s,ss(1),pad(1),order(1)
integer nn(7)
c gfortran should complain that POS and LEN are negative
print *,ibits(i,-1,-1)
c POS+LEN>BIT_SIZE(i)
print *,ibits(i,100,100)
c 30+3>32
call mvbits(n,30,3,n,1)
c 31+2>32
call mvbits(n,30,2,n,31)
c LEN negative
call mvbits(n,30,-2,n,30)
c TOPOS negative
call mvbits(n,30,2,n,-3)
c FROMPOS negative
call mvbits(n,-1,2,n,3)
end
Best regards

------- Comment #1 from kargl at gcc dot gnu dot org 2010-05-31 16:29 -------
Thanks for the bug report. Technically, the prohibition of
nonnegative is on the programmer, and as such the code is
illegal. gfortran can do anything it wants with the program
including starting world war iii. OTOH, this appears to be
a quality-of-implementation issue, and if gfortran can diagnosis
the problem, and error should be emitted.
