The following program results in a short dump, for now I've chalked it up to a bug with the ABAP compiler/run-time. Various other permutation upon the same theme runs fine... just this particular combination of dynamic class and returning a char1 to an exporting any seems to crash. (a char2 works fine, leading me to suspect UTF-16 handing bugs too)

The resulting short dump message: Access to string reference with destroyed content (it occurs on the final WRITE statement.)

To be clear I understand the error message, I just don't see how it is happening that my reference can possibly be pointing to destroyed content.

Also we have a up-to-date development system with all relevant SAPNOTES applied.

It also happens in my test system. I agree, this looks wrong. It will be interesting to test with 7.4 when such trial becomes available.

Not working on 7.4 either. Te problem is already in e_result = method_true( ) method doesn't return anything called that way. It works this way:

METHODS execute RETURNING value(e_result) TYPE char1.
 l_result = lcl_test->execute( ) .

And more important like this:

METHODS execute EXPORTING e_result TYPE string.
