*sigh*, replacing -Os to -O2 solves this bug. (see also Bug 403767) 3.7.0-r3 w/ -O2 works fine.
How is -Os making its way into the build? Is it defined in your /etc/make.conf?

(In reply to comment #3) > Created attachment 302225 [details] > /var/tmp/portage/dev-util/valgrind-3.6.1-r2/temp/automake.out oops, i did bombing error. this should be done for Bug 403779.
(In reply to comment #2) > How is -Os making its way into the build? Is it defined in your > /etc/make.conf? sorry for my bad english skill, you mean "where does -Os come from?" or "can you show me build.log?"? for former, i added -Os into CFLAGS of /etc/make.conf. and you see my emerge --info (see comment #1) has -OS in CFLAGS/CXXFLAGS. for latter, i've tried many versions. for global warming abatement, could you mind to specify version, CFLAGS and etc? :)
valgrind + compiler optimization = badness. While in an ideal world we would like to have all the flags work, I doubt its going to happen.
