Did you do a test with "-O0"? In my experience that makes valgrind tests
much more reliable and repeatable. Some time ago we've seen cases that
were failing for me but not for others, and I suspect it was due to me
using "-O0".

(This is more a random comment than a suggestion that you patch won't
make the buildfarm green.)
