Comment(by peters):

 Here is some additional gdb info at the crash point:

 (gdb) print x
 $1 = 127

 (gdb) print y
 $2 = 0

 (gdb) print z
 $3 = -1

 (gdb) print unitsx
 $4 = 128

 (gdb) print x + y * unitsx + z * unitsx * unitsy
 $5 = -750337

 (gdb) print ndims
 $6 = 3

 (gdb) print z_idx_max
 $7 = -1

 (gdb) print total_cells_coverage
 $8 = 0

 (gdb) print z_idx_min
 $9 = -1

 The negative numbers entering into the calculation for an index into
 geogstats->value looks suspicious to me, but this is the first time I've
 seen this code.
