Gdb terminates when spawned from shell

[Schmidt]

I want to spawn a GDB session from bash script and keep it working to interact it from outside. But when I start it in background (with '&' sigil)

gdb -x gdb_script.txt ./a.out < gdb_pipe.fifo &

It executes passed script and terminates by itself (I do not pass any data or signals to it)

Breakpoint 33, main (argc=1, argv=0xbffff0f4) at main.c:53
---Type <return> to continue, or q <return> to quit---53          read_main_config();
(gdb) quit
A debugging session is active.

        Inferior 1 [process 5957] will be killed.

Quit anyway? (y or n) [answered Y; input not from terminal]

What can I do to make it alive?

GDB has to run in the foreground, unless you redirect stdin, stdout, and stderr.
