Is d-profile-viewer no longer working? Or did I do something wrong?
You may have or may not have done it wrong, but in any case this is a bug. If you do something wrong, the program should tell you what you did wrong, instead of telling you that character '-' does not belong to middle of a long int.
You can try older d-profile-viewers as a workaround. Or you can try different ways to invoke the profile viewer or to profile different programs and see if you can pinpoint the cause.
