$ ./gdbserver :1234 blah
Process blah created; pid = 16471
Cannot exec blah: No such file or directory.
Child exited with status 127
Killing process(es): 16471
../../../../src/binutils-gdb/gdb/gdbserver/linux-low.c:920: A problem internal to GDBserver has been detected.
kill_wait_lwp: Assertion `res > 0' failed.
GDBserver shouldn't even be trying to kill that process. GDBserver
kills or detaches from all processes on exit, and due to a missing
mourn_inferior call, GDBserver tries to kill the process that it had
already seen exit.
Tested on x86_64 Fedora 20. New test included. I emulated what
Windows outputs by hacking an error call in linux_create_inferior.
