Gnuradio debug with gnuradio ofdm

Hello,
I was trying to use gdb with ofdm example. I called
gri_debugger_hook
in gr_ofdm_frame_sin.cc :work. However, it gives following output which
is
not what I expected. Can any one give me a help or explanation?

Thanks,
Bin

Thanks, Eric. However, there must something wrong. Because it says
fusb::_reap: Interrupted system call. Without gdb, it will go through
more
stuff. Any idea?

Thanks,
Bin

Looks good to me.

You hit the break point, and then you told it to continue.
It did :wink:
