This is probably due to the program trying to open the terminal for input. But the terminal is currently opened by gdb and not the program. The terminal emulation would normally be "VT100" or "XTERM" or "VT102" or something. So it looks like the program is unable to open the terminal, not catching the failure condition, and then trying to do something with a NULL pointer, resulting in this output. It's possible to tell gdb to read its input commands from a file, but then you cannot use it interactively. Maybe you can disable the program's attempt to read from the terminal? Or fix the source so that it handles the fail-to-open condition?
