This is bad. The python binary itself is crashing with a memory violation in C/C++ code in either Python or an external module (e.g. gevent). Unfortunately, your stack trace leaves no further hints about the source of the problem. Normally, you would compile Python and any external C modules with debugging symbols and attach a debugger. I don't know Heroku very well, but your options are probably limited. Your best bet is probably to find a reproducible test case and contact their support team.
