The structs rseq_cs and rseq are aligned to 32 bytes.
Please have a look at the bug:
"Bug 23403 - Wrong alignment of TLS variables"
(https://sourceware.org/bugzilla/show_bug.cgi?id=23403).

@Carlos or somebody else:
Should this be fixed in the upcoming glibc release?



I would consider this a block in fact.
A proper fix would have to change the way the TCB and static TLS are allocated. I don't see this as something we can pull off in the coming weeks. 

Thanks,
Florian
