Best practices to use assert and printf together

Question

I'm currently using the following statement to get assert and printf to work together, is there any better way to do this?

#define ASSERT(x) for(; !(x); assert(x))
#define ALLOC_CHECK(x, ...) ASSERT(x) printf(__VA_ARGS__ "\n");
ALLOC_CHECK(ptr != NULL, "Pointer not initialized");

You don't need to whip up your own assert() variant, you can just include an error message in the assert itself:

assert(someCondition && "Internal error: ... . Please report this bug.");

Since the assert() macro prints its argument on failure, it will also print your string.
