One advantage of open source is that users can inspect the source code.
=====
$ grep -sr 'recently re-allocated' .
	...
./memcheck/mc_errors.c:      We however detect and report that this is a recently re-allocated
./memcheck/mc_errors.c:            ai->Addr.Block.block_desc = "recently re-allocated block";
	...
=====
Then edit memcheck/mc_errors.c to read the comments and the code.
Doing so helped me understand the message.
