understood.

On the next try, if you have released a fix, let's say in 3.6.3, I will 
first launch the computation with 32bit indices.  If it fails, I will 
send you the error but.... I will have on hand a 64bit indices version 
of everything, compiled and ready to be launched just in case of error. 
  Doing so I will not loose my special cluster allocation...

anyway, thanks a lot for your help! :)
