[Zoo-discuss] SAGA_GIS Error

[Fenoy Gerald]

Dear Alex,
sorry another time for my late answer.

Thanks a lot for reporting this issue.

I have faced the exact same issue when trying to use this specific service.

Nevertheless, trying to remove the call to the Trim method (in service_internal_saga.c on line 445) solved the issue. I have committed this modifications in rev 760 [1] so this version should solve this issue. Note that gdb was of some help to identify the function which was called and caused the segfault.

I hope you can confirm that the issue is now fixed.

Best regards,
