Summary: Crash when reading extended derived type array in
namelist
Product: gcc
Version: 12.1.0

Reproducer
I get a crash when using an array of extended derived types.
If I define an other type containing the same information but not extended, the
problem disappears.
See the attached source:
> gfortran type_extends_nml.f90 ;./a.out
&NAM_BAL_NE
DATE_TIME_NE(1)%NYEAR= 2022,
DATE_TIME_NE(1)%NMONTH= 0,
DATE_TIME_NE(1)%NDAY= 0,
DATE_TIME_NE(1)%XTIME= 0.00000000 ,
DATE_TIME_NE(2)%NYEAR= 0,
DATE_TIME_NE(2)%NMONTH= 0,
DATE_TIME_NE(2)%NDAY= 0,
DATE_TIME_NE(2)%XTIME= 1.23399997 ,

Fortran runtime error: Cannot match namelist object name 2022
I tested with several versions of gfortran from version 5.5.0 to 12.1.0. All
failed.
