Here is a modified example from glibc.

...
(gdb) att 27934
Attaching to program: /home/hjl/bugs/gdb/thread/./a.out, process 27934
Child process unexpectedly missing: No child processes.
Program terminated with signal ?, Unknown signal.
The program no longer exists.

But
(gdb) att 27904
worked fine. It is a serious regression from gdb 4.18 from RedHat
6.2.
