Hi guys,

I got a trouble in line:
 /* Make sure there is at least one LWP that has been resumed.  */
 gdb_assert (iterate_over_lwps (ptid, resumed_callback, NULL));

I set a breakpoint in the begin of this function and add commands:
silent
record
c
to it.

And set a bp in the end of this function and add commands:
silent
record stop
c
to it.

And I set a bp in internal_error.

Then I found the bug.

But I found that still have 2 ways not very easy to implement. I know
nothing about it.  could you help me with it?

1. If I want get the gdb_record.xxx file of each record cycle.  It's
still hard to me.  Because if I add "record save" to commands, each
time it will save record entry to same file.
Does gdb have some way to handle it? like:
$a=1
record save $a
$a++

2.  Sometime, I want just record a function, I want:
b functon_name
commands
silent
record
finish
#Maybe we can record save in this line, this is first question.
record stop
end
But when I really do it.  I found that gdb stop running after finish.

Could you help me with them?


Thanks,
Hui
