Bug #: 13091
Summary: MALLOC_PERTURB_ and MALLOC_CHECK_=3 not documented
Product: glibc
Version: 2.14
Status: NEW
Severity: normal
Priority: P2
Component: manual
AssignedTo: roland@gnu.org
ReportedBy: karl@freefriends.org
Classification: Unclassified
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

MALLOC_CHECK_ is not obsolescent, it just doesn't take all the different
values. It continues to add checking if the value is non-zero.
