> The buffer size named buffer size_ is stored on a uint32_t.
> When the size of transmis data is above  there is an overflow and throw a bad_alloc error.
> This come from the fact that the allocated size is a power of 2 and is multiplied by 2. At a time it reach 2^32 and ask for allocating a buffer with size 0.
> Then the allocation return NULL (normal) and the exception is throw.
> Thanks to take into account the issue.
