bug in SDRAM defrag

[mrubioroy]

function defrag_free_list in libraries/ea_malloc/malloc_freelist.c contains a bug miscalculating the new block size.

After a few malloc/free operations it hangs.

line 70 should be lb->size += ALLOC_HEADER_SZ + b->size; (i.e.: replace sizeof(*b) by ALLOC_HEADER_SZ).

This bug has already been solved in the current upstream version:
libmemory/src/malloc_freelist.c

Can you post a sketch to reproduce the issue ?

Never mind, I do see the issue.
