As perhaps you have already guessed, this is just me being confused. After
removing a lot of stuff from the code, I inserted a print statement thus
620 k = max(1, shiftr(l,1)) ! The increment during the sort
621 do ! Sort constraints to make active (Shell sort)
622 do i = k + 1, l
623 print '("i=",i0)', i
The break point is at line 621. The print occurs before the break point is
reached. The print shows that all is o.k. I was confused as I thought the
breakpoint would be hit before getting into the loop. Interestingly the
breakpoint has the behavior I expected with "-O1" or "-O2".
I'm sorry to have bothered you folks with this, but I'm glad to know a little
about valgrind.
