Yes, this is issue #3461 - I already spent several hours on that error with no luck for finding the cause of it. It looks as if it was introduced without any code change. Probably when I migrated from Delphi XE to Delphi XE5, I don't know.

Fixed in r4948

Greati'll wait until this patch will come to the official release. Thanks :)
