>Description:
When I run gdb on Emacs, set breakpoint and after reaching it and typing the commands `list' and `next', gdb reports the following error:

/nevyn/local/gdb/gdb-6.3/gdb/infrun.c:2642: internal-error: insert_step_resume_breakpoint_at_sal: Assertion `step_resume_breakpoint == NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
>How-To-Repeat:
Fetch a recent Emacs CVS snapshot and compile it.  Switch to the emacs/src/ directory and run `gdb ./emacs' there.  Run the following commands in gdb:
  break send_process
  run -q
Now start a network server on the port 1234 (e.g. `socket -s 1234').  Switch to Emacs, open the attached file bug2.el and run `M-x eval-current-buffer' there.  gdb should stop on the breakpoint.  Switch to gdb and run the following commands there:
  list
  next
You should receive the error.
