Does anyone else see the following crash?
$ sh -c 'sleep 60& dtrace -P syscall -p $!'
dtrace: description 'syscall' matched 2092 probes
Assertion failed: (dpr != NULL), file
.../cddl/contrib/opensolaris/lib/libdtrace/common/dt_proc.c, line 751.
Exit 134
Also triggers without specifying PID, e.g. by ustack()
$ dtrace -P 'syscall { @[probefunc,ustack()] = count(); }'
Not sure if I hosed my environment.
