Aborting [kernel] Plug-in value aborted: invalid user input. The error message disappears if either 1) a variable (e.g. "int v;" after line 3) is declared inside class "foo", 2) the call "f.cat(f);" is omitted in line 10, or 3) the argument type of "cat" is changed to "int" in line 5 and "f" is replaced by "0" in line 10. Apparently, the "f" in line 10 somehow causes an empty struct to be generated, which is not properly accepted. ## Attachments - [116.cpp](/uploads/81a0fbdbba99b70ad2ddefa6b4bf3272/116.cpp)
