truss assertion failure report

[Mark Millard]

After setting truss to watch a couple of processes from a
poudriere session:

# truss -o ~/arm-none-eabi-gcc-truss.log -p 56361 &
# truss -o ~/ffmpeg-truss.log -p 37003 &

and later using ^C to stop the poudriere session that was
still running those processes, truss reported:

Assertion failed: (LIST_NEXT(info->curthread, entries) == NULL), function find_exit_thread, file /usr/src/usr.bin/truss/setup.c, line 416.
Assertion failed: (LIST_NEXT(info->curthread, entries) == NULL), function find_exit_thread, file /usr/src/usr.bin/truss/setup.c, line 416.

and also:

[2]   Abort trap (core dumped) truss -o ~/arm-none-eabi-gcc-truss.log -p 56361
[3]   Abort trap (core dumped) truss -o ~/ffmpeg-truss.log -p 37003



FYI:

The poudriere session was a amd64->armv7 cross-build session.
