Description Paul Floyd 2025-11-13 13:56:00 UTC 
Just one example of this:

#define FREE_SIZED(, fnname, vg_replacement, tag) \

contains

       MALLOC_TRACE(#fnname "(%p)\n", p ); \

That should be

       MALLOC_TRACE(#fnname "(%p, %z)\n", p, size ); \

I also see that there are lots of casts to ULong and %llu format strings. No casts and %zu should be enough. Lastly some of the uses of MALLOC_TRACE add "size" and "al" strings before the values. If they are never ambiguous I'll remove them.
