Harald Anlauf <anlauf at gmx dot de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |anlauf at gmx dot de --- Comment #1 from Harald Anlauf <anlauf at gmx dot de> 2012-12-23 22:17:25 UTC --- The code is rejected by nagfor: NAG Fortran Compiler Release 5.3.1(907) Error: pr46991.f90, line 16: CLASS array A must be a pointer, allocatable or assumed-shape Errors in declarations, no further processing for SUB1 Error: pr46991.f90, line 34: CLASS array A must be a pointer, allocatable or assumed-shape Changing from assumed size to assumed shape, however, make the code compilable. The code modified this way still does not compile with current trunk: A = [ (REC2(I, I+1), I = 1, 10) ] 1 Error: Variable must not be polymorphic in intrinsic assignment at (1) - check that there is a matching specific subroutine for '=' operator It is funny to see that ifort 13 generates a similar message: pr46991.f90(38): error #6197: An assignment of different structure types is invalid. A = [ (REC2(I, I+1), I = 1, 10) ] ----------------^ pr46991.f90(38): error #8304: In an intrinsic assignment statement, variable shall not be polymorphic. [A] A = [ (REC2(I, I+1), I = 1, 10) ] ---------^
