Thanks for update.
Please let me know when you will have working version of your patch.

Gcc 9.2 was OK.

If gcc produces correctly working code I think that it would be better to just
disable that single test if code with aliasing is faster.

In this actual case it is flood of such warnings when LTO is used.
Looks like glib developers are trying to tell that this those warnings should
be calmed down.
I know that LTO is pushing a lot of inlining s

Hmm .. Martin even if that can be fixed in libfabric code does it still mean
