This test script:


import re

print(re.compile(r'(?ix)A').flags == re.I | re.X | re.U)
print(re.compile(r'(?ix)A').flags == re.X | re.U)
print(re.compile(r'(?im)A').flags == re.I | re.M | re.U)


gives False, True, True on default:b28b37de9470+. Python 3.5.2 gives True, False, True.

Seems re.compile does not handle flags with X correctly?
