Note that "< inputfile.txt" is not a command line argument, but a shell 
IO redirection. Therefore without shell (or GDB) to interpret the stdin 
redirection, this won't work.
Perhaps the input file can also be specified using normal command line 
arguments?
Alternatively, you can try the GDB "set args" command in a .gdbinit 
file, though I am not sure if IO redirection is supported in this case.
