watchdogd coredump

[Alexander Leidinger]

Hi,

I updated from r239708 to r242511 and my watchdogd coredumps (and
brings down the system... well, the WD works).

Before I have a deeper look (recompiling with debugging and such) at
this, can someone confirm that with a recent -current and a WD
configured to call a shell script which does a simple ls to /dev/null
there is a segfault in watchdogd?

watchdogd_flags="-e /root/bin/wd_check.sh -s 5 -t 60"

---snip---
# cat /root/bin/wd_check.sh
#!/bin/sh

exec ls / /space/jails >/dev/null 2>&1 </dev/null
---snip---

The not so useful backtrace of the watchdogd core:
