>Description:

IPF inconsistently uses different union fiels, which happen to overlay
to the same storage on some archs but do not align as expected on others.
One example are nat->nat_osport and nat->nat_nicmpid.

>How-To-Repeat:
Code inspection.

>Fix:
Darren tracks this upstream already - hope he will have some soon.
