Ouch.  Those are the following tests?

    416. MEANS standard errors ( ok     (0m0.020s 0m0.000s)
    420. MEANS user missing values ( ok     (0m0.020s 0m0.004s)

They should not use a significant amount of memory (not if they
complete in 20 ms each).  John, you wrote MEANS, is there any
MEANS-specific reason that these tests could go haywire?

Jeremy, can you try starting one of these in a debugger, letting
it go for a second or two, then getting a backtrace?  The first
one simply consists of running the following PSPP syntax:

set format F12.4.
data list notable list /id * group * test1 *
begin data.
1 1 85
2 1 90
3 1 82
4 1 75
5 1 99
6 1 70
7 2 66
8 2 52
9 2 71
10 2 50
end data.

means test1 by group 
        /cells = mean count semean seskew sekurt.
