I'm not saying that you're wrong. I'm saying that size checking is unneccesary
in pf_integer_conv as is. All that function does is return a string
representation of a 64-bit integer. It doesn't output fields, precision, or
signs, etc. If you want to see the maximum output length of the function, do
something like this:

printf("%I64u\n", (LONGLONG)-1);

If what was converted for I64u was within 40, then that is all that is necessary.

Octal is slightly different, but it's still within bounds. I know all this
because I wrote the function and I checked to see if the function's output fit
in the buffer in all cases.
