GDB mode one `step' behind on 386 Unix/Emacs

I am having a problem using the Emacs `gdb' mode under ESIX System V
3.2.  In particular, after hitting a breakpoint, the use of the step
command always leaves the source code buffer one statement behind the
GDB buffer.  Performing a step, gdb-refresh (^L) for each keeps the
buffers in sync, but it's very inconvenient to do.  I've tried hacking
at the gdb-mode Elisp, but I've had no success.  The only (somewhat
convenient) thing that seems to work is adding a `frame' command to
the `step' command in the lisp code, so that each execution of a step
is followed by one of `frame'.

Configuration:

Hardware - 386 Clone
Software - ESIX System V 3.2D, X386 1.1b, Emacs 18.57, GCC 1.40,
	   GDB 3.5, standard `gdb.el' and `gdbsrc.el'


If anyone can be of assistance (has already met this problem and fixed
it, or otherwise), please let me know what I can do.  BTW, this
problem doesn't arise using my Emacs 18.55/Ultrix 4.1/DEC CC combo on
this machine.

Thanks in advance,
Pat
