         searchdow(NewExtWDay, -7 * OldWeeks + 6, &SplitTimePtr);
         sprintf(OldExtensions[OldWeeks], "%03d",

The first iteration of the loop is writing to OldExtensions[7], but the array
is too small in fileutil.c:

char OldExtensions[4][MYMAXEXT];

This is now fixed in CVS.

If everyone could build the latest version from CVS and test it, that would be
great.
