MacOS – OSX 10.10 Python crashing from bash

When I run Python through bash it keeps seg faulting on me. The crash happens for example if I just type >>> "\n \n, but also for a lot of other cases. From my limited understanding of the stack trace, the problem is originating from readline.so. I've googled it but can't find anything mentioning this for Yosemite. It also doesn't appear to be an issue on any other Yosemite machines I've personally used.
