Fix compiler warning in linux-namespaces.c
../../gdb/nat/linux-namespaces.c: In function ‘void mnsh_main(int)’: ../../gdb/nat/linux-namespaces.c:604:8: warning: ‘fd’ may be used uninitialized in this function [-Wmaybe-uninitialized] close (fd); ~~~~~~^~~~ And the warning is correct -- mnsh_recv_message can return -1 and leave fd uninitialized, and mnsh_main will still call close (fd) if that happens. Initialize fd to -1 to avoid that. gdb/ChangeLog: 2019-08-27 Christian Biesinger <cbiesinger@google.com> * nat/linux-namespaces.c (mnsh_main): Initialize fd (to -1).
