All of the following run without error on 9.1.3 on a Window's 2003
server environment.  I wonder if they cause problems, for others, on
9.12.

data smokecum;
  set sashelp.class;
  call missing (height);
run;

proc freq data=smokecum;
tables sex*height /  list missing ;
run;

proc freq data=smokecum;
tables sex*height  /  missing ;
RUN;

data smokecum;
  set sashelp.class;
  call missing (height);
  call missing (sex);
run;

proc freq data=smokecum;
tables sex*height /  list missing ;
run;

proc freq data=smokecum;
tables sex*height  /  missing ;
RUN;

I think we got it narrowed down a bunch.

Adding this option causes the crash/error.
OPTION MISSING=' ';

Option missing sets the character to use for displaying missing
instead of a dot.
using a space is intended to supress those dots.

with a data set where 1 of the 2 numeric vars is all missing.
and the order on the tables statement makes a difference.

ref: sas v9.2 win XPsp2.

Try this program (save your current work first):
DATA x;
  a=1; b=.; OUTPUT;
  a=2; b=.; OUTPUT;
  a=2; b=.; OUTPUT;
  a=3; b=.; OUTPUT;
  a=3; b=.; OUTPUT;
  a=3; b=.; OUTPUT;
  a=4; b=.; OUTPUT;
  a=4; b=.; OUTPUT;
  a=4; b=.; OUTPUT;
  a=4; b=.; OUTPUT;
  a=5; b=.; OUTPUT;

OPTIONS MISSING=' ';

PROC FREQ;
  TABLE a * b / MISSING;
RUN;
