Issue #12954 has been updated by Nobuyoshi Nakada.
Status changed from Open to Feedback
It's intentional that many objects (classes, methods, etc) are not freed.
Probably it's better to tell valgrind not to report such things.
Patches are welcome.

Bug #12954: valgrind shows memory leaks
https://bugs.ruby-lang.org/issues/12954#change-61597
* Author: Bernhard M. Wiedemann
* Status: Feedback
* Priority: Normal
* Assignee:
* ruby -v: 2.2.5p319
* Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN
----------------------------------------
I found that ruby itself is leaking plenty memory
in ruby2.2, ruby2.1 and ruby1.9
The only version without such leakage was ruby1.8.
Steps To Reproduce on openSUSE Tumbleweed:
zypper mr -e repo-debug
zypper in --no-recommends valgrind libruby2_2-2_2-debuginfo
valgrind --log-file=/tmp/valgrind-ruby.txt --show-leak-kinds=definite \
--leak-check=full /usr/bin/ruby -e ''
Actual Results:
/tmp/valgrind-ruby.txt shows 820KB leaked:
definitely lost: 223,845 bytes in 2,064 blocks
indirectly lost: 599,241 bytes in 11,712 blocks
It is less when running with --disable-gems but still existing.
And when adding a 'require "chef"' line, it goes above 6MB leaked.
