[ferret_users] Segmentation fault when unlabeling

[Ryo Furue <furue@xxxxxxxxxx>]

Ferret developers,

I've found an instance of segmentation fault on Ferret 6.61:

$ ferret -gif -script tmp.jnl
Cached data cleared from memory
ginqchoicest()   38 Specified workstation is neither of category INPUT nor of category OUTIN
ginitchoice()   38 Specified workstation is neither of category INPUT nor of category OUTIN
greqchoice()   38 Specified workstation is neither of category INPUT nor of category OUTIN
ginqlocst()   38 Specified workstation is neither of category INPUT nor of category OUTIN
ginqdisplayspacesize()   31 Specified workstation is of category MO
gsetlocmode()   38 Specified workstation is neither of category INPUT nor of category OUTIN
greqloc()   38 Specified workstation is neither of category INPUT nor of category OUTIN
Segmentation fault
$

The contents of the script "tmp.jnl" is

use levitus_climatology
fill/k=1/set temp
  go unlabel 10
ppl fill

When this script is run interactively, it hangs.

I have these lines in my ~/.ferret :

!set mode grat:dash
set memory/size=400
!keymark 1
cancel mode upcase_output
ppl color 3 0 70 0  !! darker green

I guess the crash is caused by the unlabeling of
a non-existent label 10.

Hope this helps,
Ryo
