    Description

      The following header file (mocds.h) does not work with moc:

      #include <QObject>
class DSTest : public QObject
{
    Q_OBJECT
    const int BAD_CONST = 0b1000'0000;
    const int GOOD_CONST = 0b10000000;
}

      Running moc on the file as-is:

      $ moc mocds.h -o mocds.cpp

      results in the dreaded

      mocds.h:0: Note: No relevant classes found. No output generated.

      If you comment out the BAD_CONST, it works fine.
