Description :

Hi. The included sample malloc.h does not compile because func is not a macro, but a static string variable. I am using clang/LLVM to preprocess my code. Also, please add "int" to the counter declaration, to avoid warnings. Thanks

C99, 6.4.2.2 #1 says:

The identifier func shall be implicitly declared by the translator as if, immediately following the opening brace of each function definition, the declaration

static const char func[] = "function-name";

Additional Information :

Please apply this patch. It's not ideal, because it uses snprintf. But at least the code is valid C:
