Comment 1. 
Category: Inconsistency
Committee Draft subsection: 6.4

Title: Constant expression cannot contain the size of a VLA

Detailed description:

6.4 does not require a constraint for "sizeof(v)" where v has variable
length array type. FN83 also fails to notice this case.

Append to 6.4p3:

    Any /sizeof/ operator shall have an operand whose size is defined
    to be constant.

Move the reference to FN83 to the new end of the paragraph, and within the
footnote change:

    not evaluated

to:

    not evaluated when no component of the operand has variable length
    array type

In 6.4p6 remove the words "sizeof expressions ... name of such a type".
