Nah. Sorry. Darn.

calloc() is working - our assert had the big bug right in the expression :-)

You were obviously much closer -

Doing the printout in ifreqNext() that you suggested, we find the size

of the first structure coming up is 70 (dec), which is not divisible by

4, which leads to the pointer to the second structure being misaligned.

Who decides the size of the ifreq structure and doesn't pad correctly?

Or should we do the padding up there?

the array returns an odd pointer.

Are we right that this is a faulty implementation of calloc()? (Which

is supposed to "return a pointer aligned to suit any type of variable"?)
