Programming :: GDB Terminates When Spawned From Shell

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).

Code: 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)

Code: 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?
