New enum type in sizeof expressions gives an error

[Rob Arthan]

The following 4 line example gives an error on line 4:

extern int a;
extern int b;
int a = sizeof(struct stag {int x, y;});
int b = sizeof(enum etag {X, Y});

as follows

Checking t.c ...
t.c:4:16: error: syntax error [syntaxError]
int b = sizeof(enum etag {X, Y});
               ^

I can't see anything wrong with the C code and nor can gcc or clang. I am using the Macports installation of cppcheck version 2.7 and the command line was:

cppcheck t.c

Using --clang provides a work-around, but I am mainly interested in the MISRA add-on and that doesn't seem to work with --clang.

I appreciate that the example is fairly silly C, but I am writing test cases and want some obscure examples of type introduction.

The code is attached.
