hi tony,
[ruby-core:68420] [Ruby trunk - Bug #10931] [PERF]bm_app_mandelbrot.rb 20% slower.

ruby-core #68420
Issue #10931 has been updated by Nobuyoshi Nakada.
On MacBook Pro late 2013, OSX 10.10.2, 2.6GHz 16GiB.
At a git-svn working directory, (`$build` is the build directory):
~~~
$ execs=; for c in `git log --since=2015/2/1 --format=%H --reverse -- complex.c`; do v=`git log -1 $c | sed '/git-svn-id:/!d;s/.*@//;s/ .*//'`; git co $c -- complex.c numeric.c && echo $'#define RUBY_REVISION '$v$'\n#define RUBY_BRANCH_NAME "bm_complex"' > revision.h && rm -f $build/{complex,numeric,version}.o && make -C $build EXEEXT=-$v mini && execs="${execs};r$v::$build/miniruby-$v"; done && ruby benchmark/driver.rb -fm -e "${execs}" -p mandel
~~~
