Please ignore the patch (I should have said it was inelegant and did not work).
The bug is real, however. See below.

Similar (stream separation) problems occur with GDB output running
multi-threaded programs. However, I don't know how much effort you are
prepared to spend on annotations. If you guide me I can look at annotate.c.
Jim Blandy has suggested using the tty command for stream separation but
presumably this wouldn't work on Windows.

example.c:

myproc()
{
  int j;
  j = 1;
}

main()
{
  int i;
  i = 1;
  myproc();
  i = 2;
}

Start like:
gdb -ann=2 example

Type:
set height 0
b myproc
run
finish


Output:
(Frame details are given before the stopped annotation and so appear to
be program output)
