  gcore, a subcommand in GDB providing the feature of producing a core
  dump for currently running processes, produces a broken core dump when
  the target program sleeps.

  Step to reproduce:

  $ cd /tmp
  $ gcc -x c - -o loop
  #include <unistd.h>
  main(){for(;;)sleep(1);}
  $ ./loop &
  [1] 3598
  $ gcore 3598
  0x00007f78bb59e370 in nanosleep () from /lib/libc.so.6
  Saved corefile core.3598
  $ gdb loop core.3598
