OK, I see that the warning is misleading, because it points to the call of
vsnprintf instead of pointing to vsnprintf_one.

ttest.c: In function ‘vsnprintf_one’:
ttest.c:826:5: warning: function might be possible candidate for ‘gnu_printf’
format attribute [-Wmissing-format-attribute]
     vsnprintf(self, 2, "%c", arglist);
