Compilation failed: unrecognized character after (? at offset 11

[chayden]

This message seems to coming from the News module, which has some routes that use the regular expression containing (?P.
As far as I can tell, this is not legal PHP.
How can this be working for people?
Is there something that is supposed to pre-process these things out of the regular expression, that is not working in my environment?

May be this is true. But please tell us more how to reproduce the problem or to diagnose how it comes up.
Usual questions : hosting, OS, versionS, setingS, install procedure, warnings...
