I am sure. I have multiple builds that I switch between. One of the
apps doesn't work unless I --without-memory-manager (see post to
-users about realloc(), with sample code).
I noticed that there are a few ./configure --debug type switches, even
some dealing with memory. Could those be useful for gathering further
data? What features do those provide and how do I use them?

I should clarify here, this is effectively true. The app crashes from
a segfault after running over tcp for several hours, but it gets much
farther into the run than the vapi btl does.
