[bug] Kernel processing infinitely with using keyword for type declaration

[anutosh491]

Both native/wasm kernel end up infinitely processing

I guess we are not recovering the error well somehow. Shown some examples where stuff works, then the main example where the kernel runs infinitely

We should just probably see something like this instead of the kernel running infinitely

: error: expected ';' before '}' token
    4 |     using type = int
      |                     ^
      |                     ;
    5 | };

On Clang-repl I see

anutosh491@vv-nuc:/build/anutosh491/llvm-project/build/bin$ ./clang-repl
clang-repl> struct X { using type = int };
In file included from <<< inputs >>>:1:
input_line_1:1:28: error: expected ';' after alias declaration
    1 | struct X { using type = int };
      |                            ^
      |                            ;

Which means we are catching the error but something leeds to an infinite loop !
