/* Special value for CRT to prevent heap overflow into address space hole:
_sbrk assumes the RAM between _end and _estack is contiguous and prevents
heap overflowing into the stack by checking that the heap end pointer is
never going past (_estack - _Min_Stack_Size).

By setting _Min_Stack_Size to this value, we ensure that _sbrk considers the
end of RAM_D1 as the heap's upper limit, preventing reserved memory space from
being used as heap memory improperly.
