Then it's not really a simple test case. To me, a "simple testcase" would
involve seeing if you could hack out all the actual serial comms stuff,
replacing the input with say reading data from an array and replacing the
output with dropping it on the floor, so that you stripped down your app to
the basics: two threads talking to each other using cvars and mutexes to
operate a message queue between them.
In the course of stripping it down, you might well find the problem
disappeared when you removed a certain area of code, which would give you a
big clue to where the problem was arising. Sometimes, just /attempting/ to
make a testcase is enough of a debugging effort by itself. If not, at least
you have something that other people can just run and try to reproduce and
debug the problem.

You misunderstand the GPL. You cannot forbid someone from distributing the
derived work under any circumstances. You can ask them nicely to voluntarily
not distribute it, but the agreement would not in any way be binding, and they
would still have a legally-enforcable right to redistribute it, regardless of
any personal understanding you may have reached between yourselves; gpl rights
cannot be waived.
