Description Karl Berry 2011-08-14 23:27:39 UTC
In the manual, memory.texi (node Heap Consistency Checking) talks about the envvar MALLOC_CHECK_ for values <=2.  

I've learned that it can now also be set to 3, and there's an additional related envvar MALLOC_PERTURB_.  Please document those too?

Thanks,
Karl
