Now I get a different problem.  With this source file:

    DATA LIST FIXED 
            FILE='cvs-hist'
            /RTYPE 1-1 (A)
            WHEND 3-12 (SDATE)
            WHENT 14-18 (TIME)
            WHO 26-33 (A)
            WHAT 40-70 (A)
            .

    VALUE LABELS /RTYPE 'A' 'Added' 'M' 'Modified' 'R' 'Removed'.
    VARIABLE LABEL WHAT 'Filename'.
    VARIABLE LABEL WHO 'Developer'.
    VARIABLE LABEL WHEND 'Date'.
    SPLIT FILE BY WHO.
    FREQUENCIES /RTYPE.
    SPLIT FILE OFF.
    COMPUTE T= 86400 * XDATE.JDAY(WHEND).

    COMPUTE WHAT=RTRIM(WHAT).


    SORT CASES BY WHAT, T (D).
    SPLIT FILE BY WHAT.

    * Number of days between file modification
    COMPUTE DIFF = LAG(T) - T.
    COMPUTE DIFF = DIFF / 3600 / 24.

    VARIABLE LABEL DIFF 'Time between modification'.

    LIST.
    EXAMINE DIFF 
            /STATISTICS = DESCRIPTIVES
            /PLOT = NPPLOT
            .

I get a segfault:

    (gdb) r

I think this is your code so I'll let you take the first stab at
it.
