           Summary: clang++ fails to allocate a "float (*)[height]" to
                    "float (*)[height]" object

Clang++ (version 7.0.0 (trunk 334413)) fails to compile the following code

#include <stdlib.h>
void allocateArray(int height) {
        float (* Ix)[height];
        Ix = (float(*) [height]) malloc(sizeof(float)* (height));

clangBugCheck.cpp:4:7: error: assigning to 'float (*)[height]' from
incompatible type 'float (*)[height]'
 Ix = (float(*) [height]) malloc(sizeof(float)* (height));
1 error generated.

Command used to compile code: clang++ filename.cpp -c

GCC and ICC are able to compile the code.
