Summary: Uninitialized parameters to
VALGRIND_MAKE_MEM_NOACCESS() not warned about.
Product: valgrind
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED

Component: memcheck
Assignee: jsew...@acm.org

(Forked from https://bugs.kde.org/show_bug.cgi?id=144362#c2 .)
Uninitialized parameters to
VALGRIND_MAKE_MEM_NOACCESS()
VALGRIND_MAKE_MEM_UNDEFINED()
VALGRIND_MAKE_MEM_DEFINED()
should be reported. See
https://android-review.googlesource.com/#/c/307010/14..15/runtime/base/arena_allocator.cc
where it took a long time (and some luck) to track down the uninitialized value
being passed to VALGRIND_MAKE_MEM_NOACCESS().
Note that the current version of valgrind in AOSP is valgrind-3.10.1 .
