           Summary: ctRegex does not work when using alternatives ('|')
                    involving a '+' inside non-capturing group ('(?:…)')
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: rejects-valid
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: kennytm gmail.com



Test case:

------------------------------------------------------------------------------
import std.regex;

// using capturing group has no problem.
enum bug7440a_1_workaround = ctRegex!`(b*|d+)`;
enum bug7440a_2_workaround = ctRegex!`(a|b+)`;
enum bug7440a_3_workaround = ctRegex!`(a|[^a]+)`;

// using '|' inside a '(?:...)' may cause InfiniteEnd or some other error.
enum bug7440a_1 = ctRegex!`(?:b*|d+)`;
enum bug7440a_2 = ctRegex!`(?:a|b+)`;
enum bug7440a_3 = ctRegex!`(?:a|[^a]+)`;

Not a Phobos bug. It's in CTFE side of things. Nowadays it triggers assert.
Judging by the assert firing off it's a likely duplicate of Issue 7810.
Issue 7810 also features smaller test case.

Now 7810 is fixed and I see that this bug is a different beast, will look into
reducing it more.
