We have the following scenario:

Two memory areas, one is fixed 2 MB size, the other may 2 MB or 0 MB. In the first area we have heap1, heap2 is in the second area. HAL_MEM_REAL_REGION_TOP handles this pretty well, but when the constructor of Cyg_Mempool_Joined is called it fails when heap2 is 0 MB size. That should be fixed by my patch.

Cheers,
Dirk
