"Of course it does, because without aligning the container you cannot have
aligned members. Maximum alignment always propagates outwards."
Sorry, your answer is still not clear, so let give a short

One more thing. I would expect that the issue would be in CTimeHistogram
functions (defined as aligned) but the code generation issue was in the parent
object ( CCPortLatency)
Why the compiler assumed that

After some investigation, I think it is not a gcc issue, please verify.
One of the internal object does not include a 64B alignment.
#define __rte_cache_aligned __attribute__((__aligned__(64)));

The global/parent object CGlobalTRex is aligned (64B) as expected:
(gdb) p _trex
$1 = (CGlobalTRex *) 0xc365c0
Could you explain why it is a problem to define the internal objects with the
aligment like

--- Comment #13 from Hanoch Haim ---
One more thing, The parent object is defined with 64Byte alignment
class CGlobalTRex {
..
} __rte_cache_aligned;
static CGlobalTRex trex;

--- Comment #11 from Hanoch Haim ---
thanks for the quick answer.
The parent object is static (bss) and wasn't dynmicly allocated using
new/malloc.
gcc set the address of the parent object and the childs.
Is there a way to solve it without

With Ubuntu gcc7.4 package, there is no bug.
I've built the gcc from source and it has an issue. There are a diffrent
