yes, and I think it correctly detects that it is running interactively. > If it does, and bash uses a pty (which is a pipe, not a console), then > the application may decide that it's not running interactively > (disabling the history mechanism). what is the function call that does that? how can an application disable the history mechanism?

I do not observe this: the application interaction appears right under the gdb prompt, the screen is not cleared. > If my guess above is correct, there is no way to fix this short of > always opening the application in its own console (or fixing the > application code, if it's available). the application is CLISP (GPLed ANSI Common Lisp implementation, so, yes, its sources are available and fixable).
