    Description

      moc exits with a failed assert when run on the attached malformed file:

      ASSERT: "uint(i) < uint(size())" in file ../../../include/QtCore/../../../../../src/qt-5.7.0/qtbase/src/corelib/tools/qbytearray.h, line 480

      It's clear that moc can't generate something useful from this file but still it should not crash. Qt 5.6.1 finished safely with an error message:

      ""
crashmoc.h:2: Error: Unexpected character in macro argument list.

      This is not a duplicate of QTBUG-53441 which is fixed in 5.7.0.
