FWIW:

I believe that at least some of the connect over TCP changes are also merged
into the cvs main trunk branch on launch pad, which I am working on. I have
a strong suspicion that I have resolved another (I don?t know if its related
to above mentioned issue or not) circuit shutdown related bug there today by
switching the order of these two fields in class tcpiiu. This exact issue
does not appear to be in the R3.14 trunk, but nevertheless I thought you
might benefit from my experience in case a similar issue is occurring there
in R3.14. The failure was related to the free list being destroyed before a
class that was using it was destroyed (which causes the memory where objects
live to be deallocated before they are destroyed).
