With LWP? Probably not usefully.

Could try printing the contents of the conn and call:

frame 7
print *conn
up
print *call

LWP is going to confuse valgrind, so you get a lot of not-useful stuff.
If you can get it to crash while under valgrind it might output
something helpful, but as I recall, most of what you get is trash. But
if we can look at it, we may be able to find something.
