Actual Results: segfault Expected Results: ps axl output so I can find child processes Additional info: As with all segfaulters, this has a potential to be a security issue, however remote. I'll enter the severity as normal, however, because a practical means of exploiting this eludes me.
This was a bug in the wchan symbol decoding. It will be fixed in 2.0.12-1.
I've build and tested this, it'll be in rawhide shortly.
