Python crashes while executing the following code using the new regex module. Have I made a mistake?

import regex as re
rx = re.compile(r'\bt(est){i<2}', flags=re.V1)
print "Prints here"
rx.findall("Some text") # Python crashes
print "Fails to print"

I get the same results using 64-bit and 32-bit Python on Windows 7 (64bit) when using regex-2013-10-04 and regex-2013-08-04. However, the code does not crash when using regex-2013-03-11.

The regex module is a third-party project and is not part of the Python standard library. I suggest you open an issue on the issue tracker for the project and include more detailed information about the problem:
