You're too kind.  I'd say it borders on contradiction:
4.6.2.1 : "...the longjmp function shall execute correctly in contexts
of interrupts, signals and any of their related functions."

But of course not signals caused by interrupts.  Anyway, 4.7
is more restrictive so it wins.  Thanks for helping me understand
the situation, I won't bring it up again (and I'll be much more
wary of longjmp's in handlers).  You forgot to mention another
relevant part of the Standard, on pg.1 footnote:
	"The Standard ... is not a tutorial."
