Issue #3221 has been updated by yellowrabbit2010.
v5.7.0-1344-g3af807019f Since it seems like some of the crashes are related to tp->mags[0].prev, I tried to set a watchpoint for this field. I don’t know how well it turned out. If I did something wrong, then correct me. I built libc and dntpd (yeah, this is another program that breaks, I just did not notice it because it starts) with debug information. ====================================================== Reading symbols from /usr/sbin/dntpd...done.
