So you have some kind of bug in your inferior function call
implementation.  For some reason gdb doesn't regain control
after the call ends.  At this point I'd just switch to reproducing
the problem manually while debugging gdb, and try to figure
things out.
Did this work with 7.2?  That should make things easier,
as you have a basis to compare.  Maybe something to do
with the fact that we now default to putting the call
dummy on stack, while it would go on entry before.
