Use PLATFORM(BREWMP).

OK, but lets fix Assertions.h for the COMPILE_ASSERT problem.

If you're mallocing locally, you should use an OwnPtr.  Or maybe a Vector<char> here.

Remove #undef COMPILE_ASSERT and use Vector<char>.

If any of these errors are false positives, please file a bug against check-webkit-style.

It seems that check-webkit-style complains about NULL in the comment.

Replace NULL with 0 in the comment.

I probably would have made the while loop its own function which took a Vector<char>& and knew how to walk the vector spitting out chunks to the debug stream.

This should probably just be "static":
 123     char printBuffer[printBufferSize + 1];

Can VSNPRINTF ever return < 0?  If so, then this code can deadlock.

I guess I would have used buffer.size() to bound my while loop instead of the return value from VSNPRINTF.  That way you know for sure that you never walk off the end of the Vector.
