--- Comment #1 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
Well, its not really a 'crash', but certainly not correct.

Comment out the READ statements and look at the result:

$ ./a.out=20
&NAM_BAL_NE
 DATE_TIME_NE(1)%NYEAR=3D0          ,
 DATE_TIME_NE(1)%NMONTH=3D0          ,
 DATE_TIME_NE(1)%NDAY=3D0          ,
 DATE_TIME_NE(1)%XTIME=3D  0.00000000    ,
 DATE_TIME_NE(2)%NYEAR=3D0          ,
 DATE_TIME_NE(2)%NMONTH=3D0          ,
 DATE_TIME_NE(2)%NDAY=3D0          ,
 DATE_TIME_NE(2)%XTIME=3D  0.00000000    ,
 /
&NAM_BAL_E
 DATE_TIME_E%TDATE%NYEAR=3D0          ,
 DATE_TIME_E%TDATE%NMONTH=3D0          ,
 DATE_TIME_E%TDATE%NDAY=3D0          ,
 DATE_TIME_E%YTIME=3D  0.00000000    ,
 /

The extended type is not even being seen as an array=
