Right now the free() call is not intercepted since all this is done using macros and that would break a lot of stuff. Instead a __free() macro was provided but never used. In addition it used to only report a zero size, which is not very convenient. With this patch comes a better solution. Instead it provides a new will_free() macro that can be prepended before a call to free(). It only keeps the counters up to date, and also supports being passed a size. The pool_free_area() command now uses it, which finally allows the stats to look correct: pool-os.h:38 MALLOC size: 5802127832 calls: 3868044 size/call: 1500 pool-os.h:47 FREE size: 5800041576 calls: 3867444 size/call: 1499 The few other places directly calling free() could now be instrumented to use this and to pass the correct sizeof() when known.
