hi,all

I meet a strange problem. I first alloacte a block for some variable, I want 0x400000 align. In the following ways:
spdk_dma_zmalloc(buf_size, 0x400000, &dma_addr);
It return 0x7ffff2600000.And then the next malloc get coredump. the address of elem in malloc_elem_free_list_insert equal to the prev malloc address.

(gdb) bt
#0  0x0000000000431b70 in malloc_elem_free_list_insert (elem=0x7ffff2600000)

#6  0x000000000041954a in spdk_dma_zmalloc (size=48, align=0, phys_addr=0x0) at env.c:84

Is there some limitation for using spdk_dma_zmalloc?
