[ncl-talk] fatal:["Execute.c":8640]:Execute: Error occurred at or near line 897 in file $NCARG_ROOT/lib/ncarg/nclscripts/csm/crop.ncl

Guido's response is correct.

Still, a 'trick' when encountering a malloc error is to use a small subset
of the data

Rather than:

  tasmax = a->tasmax

  tasmin = b->tasmin

  Pr_annual_total  = c->pr

  lon = a->longitude

  lat = a->latitude
  time = a->time

Use
  NT = 100                                    ; arbitrary

  tasmax = a->tasmax(0:NT,:,:)

  tasmin  = b->tasmin(0:NT,:,:)

  Pr_annual_total  = c->pr(0:NT,:,:)

  lon = a->longitude

  lat = a->latitude


Note: rather than reading the 'time' variable directly
  time = a->time(0:NT)
I suggest using the 'time' coordinate associated with the variable
   time = tasmax&time
