This is intentionally not specified.  After your string1() function returns,
the value of ap in the string1_or_2() function is indeterminate; if you want
to continue using it in a strictly-conforming program you must invoke
va_end(ap) then another va_start(ap,dummy), which will reset the pointer
to the start of the variable argument list.

This was thrashed out in committee; please don't argue about it now.
