runtime: unexpected return pc for runtime.systemstack_switch #35592
Milestone
Comments
This is almost certainly the same issue as #35689. Note the similarity between the bad words at the top of the stack (478882bf1e330a7e, d32669b5054179d9, etc) and the bad pointers in the stack trace from #35689 (637469796d2f656d). My guess is that this is related to Linux 5.3.x, but waiting for confirmation in #35689. |
Kernel version confirmed. Folding into the super-bug (#35777). |
