--- Comment #10 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> --- well, maybe a more simple reason. If I export export OMP_STACKSIZE=32M (i.e. stack size for the threads), the segfault disappears... does that sound like a good reason (i.e. tsan instrumented binary might require more stack), or does this seem just lucky coincidence ?
