Valgrind issue on 64-bit arch linux

A few days back, I was using valgrind on Ertf; when I stumbled upon an interesting bug. On 64-bit Arch linux systems, valgrind 3.5.0-5 was showing a problem with getimeofday(). Finally, I had found a problem with Arch linux [the first since installation.]. However, the very next day,

pacman -Syu

showed valgrind 3.5.0-6, which had the bug fixed. To nail down the bug, I had tested valgrind with a simple program calling ecore_time_get(). The output is below.
