When shrinking a chunk allocation, compare the size of the current 2017-01-21T07:47:42+00:00 otto 2017-01-21T07:47:42+00:00 urn:sha1:9d0ad2ad94663962dbaafbd967e30ac985f4dc22 allocation to the size of the new allocation (instead of the requested size). 2. Previously realloc takes the easy way and always reallocates if C is active. This commit fixes by carefully updating the recorded requested size in all cases, and writing the canary bytes in the proper location after reallocating. 3. Introduce defines to test if MALLOC_MOVE should be done and to compute the new value. Remove unnecessary casts of 'a' to char * since 'a' is already char *. 2017-01-04T15:20:30+00:00 millert 2017-01-04T15:20:30+00:00 urn:sha1:da00babddfa64469738880736e1d616936cc2b95 This is a remnant from the original 4.4BSD code that had 'a' as void * in the function args. No binary change.
