Here is the line that causes the segfault:
https://github.com/shoebot/shoebot/blob/shoebot-gtk3-pgi/shoebot/sbot.py#L76
from shoebot.grammar import DrawBot, NodeBot
If I change it to only import one of these then it doesn't segfault. S++

Hi, I'm running pypy 2.4.0 on Ubuntu Utopic.
Running the pypy works OK (though it outputs 'trusty' weirdly):
$ pypyPython 2.7.8 (2.4.0+dfsg-1~ppa2+trusty, Sep 25 2014, 04:35:04)[PyPy
2.4.0 with GCC 4.8.2] on linux2Type "help", "copyright", "credits" or "license"
for more information.>>>>
Running my program in it gives a segfault:
$ sbotSegmentation fault
If I run in CPython then things are OK
$ sbotusage: usage: sbot [options] inputfile.bot [args] [-h] [-o FILE] [-w]
[-f] [-t TITLE] [-s] [-dv]
[-p SERVERPORT] [-r REPEAT]
[-g GRAMMAR] [-c] [-v VARS]
script [script_args]usage: sbot
[options] inputfile.bot [args]: error: too few arguments
I got this out of gdb:
