Unfortunately, since libinproctrace.so does not link to gnulib, we can't use it there, especially since it still includes the gnulib headers (so it is difficult to directly call the system strerror_r). gdb/ChangeLog: 2019-11-26 Christian Biesinger <cbiesinger@google.com> * linux-nat.c (detach_one_lwp): Call safe_strerror instead of strerror. * nto-procfs.c (nto_procfs_target::create_inferior): Likewise. * windows-nat.c (windows_nat_target::create_inferior): Likewise. gdb/gdbserver/ChangeLog: 2019-11-26 Christian Biesinger <cbiesinger@google.com> * debug.c (debug_set_output): Call safe_strerror instead of strerror. * linux-low.c (attach_proc_task_lwp_callback): Likewise.
