I tried the original reproducer on a patched kernel, and it looks good. GDB's behavior is still not super clean when this situation happens: a PTRACE_GETREGS on the (disappeared) leader now fails with ESRCH (that's what we want), and that interrupts the "continue" command and unexpectedly brings back the prompt while leaving the other thread running. But that is all logic that will have to be fixed inside GDB. So, feel free to add Acked-by: Simon Marchi <simon.mar...@efficios.com> too. Thanks! Simon
