Hi Dominique,

I have read exactly this:

> 3 If the variable is an unallocated allocatable array, expr shall have the same
> rank. If the variable is an allocated allocatable variable, it is deallocated
> if expr is an array of diff\verent shape, any of the corresponding length type
> parameter values of the variable and expr diff\ver, or the variable is
> polymorphic and the dynamic type of the variable and expr diff\ver. 

this section explicitly says it is deallocated only if the shape is different.
In my example, the shape is the same (even if the bounds are different). 

There is thus no need to deallocate a, and reallocate afterwards with the
bounds of b.

Joost
