Recursive functions returns different values

[seekworser]

After digging around a bit more, I found even weirder results. when I fix 
initial size of hash table, it returns different value. When I modify line 3 of 
my original code to
    
    
    var dp = initTable[int, int](4)
    
    
    Run

so that resize should not be occur, and it also returns 5, which isn't the same 
as my first result.

Modifying line 3 to
    
    
    var dp = newSeq[int](4)
    
    
    Run

also returns 5, so I suspect something occured while resizing hash table.

I'll also try gdb debugging, but post just as a quick note.
