Create a core file of GDB? (y or n) n
Note that the problem is caused by the shell dying.
It is fairly easy to trigger this problem by accident if you happen to
have a file with parentheses in its name, because the readline tab
completion in gdb's command line will fill in the file's full name
without quoting or expanding the parentheses.
