Valgrind crashes on MT7621 (MIPS 1004Kc)

Hi! The Openwrt-Package for Valgrind seems to be well maintained but unfortunately it crashes on an MT7621 based board.

Maybe somebody can provide a brief hint if the combination Openwrt (Nightly) + Valgrind + MT7621 (MIPS 1004Kc) is known to work. Or maybe known to be broken.
