Hi.
I'm seeing a python back trace when I attempt to debug from a core dump
file. I create a core by building and running the following code:
int main()
{
int* p = 0;
*p = 20;
}
gcc -o test test.cpp
./test
And I'm starting pyclewn with
python -m clewn -e vim -l nbdebug -f out.2
--or--
python3 -m clewn -e vim -l nbdebug -f out.3
And run the following commands from inside vim:
:Cfile ./test
:C core-file core
I see a "Connection reset by peer" error flash on screen and the following
back trace is written to the log. (Note, the python3 back trace is very
similar but uses asyncio not trollius.)

If I run the program from inside vim debugging works as expected. I can
provide the full outputs of python and python3 runs if needed.
I'm using:
pyclewn: 2.0.1
vim: 7.4
ubuntu: 14.04
gcc: 4.8.2
Many thanks for a great program,
Steve
