Except to let you know your code sample link is broken.

FWIW, I get the same error, and I get a similar one in LDC:

Well, it should have said "sorry, unsupported yet" or something to that 
extent. It's a bug regardless as it shouldn't spit this much of garbage 
on the screen.

ctRegex is not yet up to the full feature set of the run-time one. The 
prime things missing are exactly zero-width assertions 
(look-ahead/look-behind). And certain things will simply make compiler 
explode...

Reasons for not supporting it yet are various but the primary one is 
that I can't even fully test the current subset yet (!) due to the sorry 
state of CTFE (still!). Things definitely greatly improved since then 
but don't get your hopes high it's not something to fix overnight.
