looks like a passing by reference problem. if you add debug to look
at the address of ifitQ at all stages, you'll notice that the copy pointer
in readCharges2 gets changed, but that isn't the same pointer as in
the calling block.

see section 2.17 of http://www.lysator.liu.se/c/c-faq/c-2.html

i don't understand how linux is getting it right tbh.
