Hi,

the attached code fails at runtime as follows:

% ./a.out
 calling cg...
 cg: before g%assign
 Oops in concrete_vector::my_assign : wrong type

Interchanging the indicated use statements in the main
program leads to:

% ./a.out
 calling cg...
 cg: before g%assign
 cg: after  g%assign
 after cg...

The code works flawlessly with nagfor 5.2,
xlf 12.1 and xlf 13.1.

Cheers,
ha
