Just to be clear about the current situation:
The function call types used by the regex lib are designed to always match the call types used in the binaries. Further, you absolutely can not mix a release binary in a debug build or vice versa - they use different runtime libraries.
As I said previously, this prevents an awful lot of support calls for me, so it's not going to change unless *lots* of people complain, and at present I don't see that.
