Hi Jürgen: I've got code that works except for bugs unconnected with the GNU APL routines.
I decided to implement the interface as a wrapper for an item of type `const Value_P&`. API.cc contains the following lines: // The commented-out variants give segmentation errors, I don't understand why. // Maybe needed only when `value` is Value*. not when it is already Value_P. // Jürgen will know. // #define PCLONE(valuep) valuep // #define PCLONE(valuep) Value_P(valuep) #define PCLONE(valuep) *(new Value_P(valuep)) I.e. instead of initializing the item as e.g. `symbol->get_value()`, I initialize it as `PCLONE(symbol->get_value())`. I have not laboriously checked in which places this additional `new` is really necessary, all I know is that it is necessary for at least one of them. Best wishes Dirk
