The fix appears to work only when NULL is passed for the array. If you pass an
actual array (e.g. in the following modified test case), clang still exits with
the original error.

void function(short width, int data[][width]) {}
void test() {
     int bork[4][1];
     function(1, bork);

clang: CGExpr.cpp:1169: clang::CodeGen::LValue
clang::CodeGen::CodeGenFunction::EmitDeclRefLValue(const clang::DeclRefExpr*):
Assertion `V && "DeclRefExpr not entered in LocalDeclMap?"' failed.
