I don't know how to do this directly but there is a brute force way to do this
using gdb attach.
Change your main with
volatile int spinning=1;
main()
{
while(spinning){}
...
}
Now you can launch
$ ./foo <foo_input
which will get stuck in the infinite loop
From a separate terminal
$ ps -ef
find the process number, say 12345
$gdb foo
(gdb) attach 12345
Set spinning to zero
(gdb) p spinning = 0
...
