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.

Has more tests but with the same root cause as 9634.

*** This issue has been marked as a duplicate of issue 9634 ***
