Clang problem reading wild cards

Clang has problems reading wild cards such as "(U|k|epsilon|s).*". It doesn't expand it correctly thus, the error: Entry 'epsilonFinal' not found in dictionary.....

@Sergio Any specific version of clang?

Nothing like 00717265b57aa33033b772c7bcadd55f14ef25a9 I suppose?

Note that you can use applications/test/regex1 when testing suspicious looking regexs.

Clang701. The expression: "(U|k|epsilon|s).*" Cannot find 'epsilonFinal' not found in dictionary. Gcc is working of course.

As a temporary workaround (don't commit until we get to the root of this, you can change your local src/OSspecific/POSIX/regExp/regExpFwd.H file

// Newer compilers support regex directly
#if (_GLIBCXX_RELEASE >= 7)   /* issue #1389 Clang problem??  || (__clang_major__ >= 7) */
typedef regExpCxx regExp;
#else
typedef regExpPosix regExp;
#endif

but need to really check more

Thanks. I'll check it.
