Hi Caolan,
Of course your right in that debug support in the new (rtl_cache based)
allocator is very limited. Unfortunately, your "crude" patch will not generally
work (besides its performance impact) as the previously free'd object may not be
in the current magazine ("curr").
Please allow for a couple of days to work out a more general solution; the
pieces are already there (FLAG_NOMAGAZINE can force the cache to use the slab
layer only, and the slab layer can be made to keep track of all buffers in a
hash table) but I need to find some time to actually make these changes.
Of course, my proposed changes also have a negative performance impact, and will
also (possibly significantly) increase the amount of memory used (additional
hash table space). So, this can only be enabled in non-pro builds which are
probably not in wide spread use.
Probably, the only reliable way to detect such issues is through use of valgrind
(and friends).
Hope that helps,
Matthias
