I've been poking through the open bugs and patches(*). I've run across a few bug reports about this. There is a very brief mention of this problem in the re module doc: sre is the default implementation and includes Unicode support, but may run into stack limitations for some patterns. I recently added an example that demonstrates the problem, but I think the main issue is that the limitation needs to be better documented. We can then close most/all of these bug reports as "not a bug" or "known implementation limitation". Does this seem like the right approach?

As long as all the stack overflow possibilities are protected with PyOS_CheckStack() calls. In the past that wasn't always the case, and this created havoc on operating systems without hardware stack limits.
