Same thing happens here. What's that supposed to do anyway? 
Should be fixable with a bit of defensive coding. (The one good thing
about core dumps is that it is fairly easily to pinpoint where the
problem is...)

Fixed now. 

[In src/main/bind.c, just after line 913, insert

                               if ( k == 0 )
                                       mrows = 0;

]

I made this change, so the lines around 913 are now

     STRING(result)[i + n + (j * rows)] = STRING(u)[(i + j * mrows) % k];
    n += mrows;
                              if ( k == 0 )
                                       mrows = 0;
   }


and recompiled, but I still get the same problem:

Aw, darn ...

Someone must have been adding stuff to my version but not yours...

The lines need to go  *before* the outer for loop. After line 909,
that is.
