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]+)`;
