Constructors for Parametrized Derived Types

Constructors for Parametrized Derived Types

In my attempt to use a parametrized derived type by initialization, I received a "Internal Compiler Error". Before filling in a software problem report, I want to ask may there be something wrong about below code snippet and the related behavior:

      type :: flexible_data (k)
         integer, len :: k
         character(len=26),dimension(k) :: variable_size_array
      end type

      type(flexible_data(3)) :: FlexData1 = flexible_data(3)(['XYZ','YZX','ZXY'])

The compiler outputs the following error: ("Compiling with Intel(R) Visual Fortran Compiler XE 15.0.4.221 [IA-32]")

1>catastrophic error: **Internal compiler error: internal abort** Please report this error along with the circumstances in which it occurred in a Software Problem Report.  Note: File and line given may not be explicit cause of this error.

If I change the length of character to 25 (I am especially using 25 and 26 in order to express the problem; actually which I don't expect to be special numbers), the compilation succeeds without error. However the code snippet above seems to be compatible with specifications in https://software.intel.com/en-us/node/678531.

Furthermore If I attempt to use below line instead of the above initialization (considering examples at https://software.intel.com/en-us/node/678530):

      type(flexible_data(:)), pointer:: FlexData1 = flexible_data(3)(['XYZ','YZX','ZXY'])

Regardless of the length of the character in definition, the compiler outputs again the "Internal Compiler Error".

For more complete information about compiler optimizations, see our Optimization Notice.

An internal compiler error is ALWAYS a compiler bug. That said, you are using a three-year-old compiler and your first example compiles successfully with the current version 18 compiler.

The second example is not valid Fortran.
