Created attachment 370780 [details, diff] patch for symbol ptrace_peeksiginfo_args sys-process/criu-1.1 needs a patch to compile since the symbol ptrace_peeksiginfo_args is no longer known.
This patch should be conditionalized so the code continues working with <glibc-2.18 otherwise I doubt upstream will accept it.
