Comment (by rhaas):
This still happens even with current (Sun Mar 22 18:46:21 CET 2015) trunk, though failure looks a bit different now: {{{ actus_sim: /data/rhaas/postdoc/gr/ET_trunk/configs/sim/build/LoopControl/loopcontrol.cc:312: T {anonymous}::divexact(T, T) [with T = int]: Assertion `i % j == 0' failed }}}
