I start the program with a console command.

OK. You still missed to provide information on how you start the
crashing program from the remaining program - certain approaches don't
allow simple access to the result (e.g. checking whether it's still
running or accessing the process exit code), whereas others do. However,
in general, you need to redirect the output and stderr handles (e.g. to
a pipe if doing it under Linux, but a file would do as well) and read
them from the remaining program. As an example, TProcess (in unit
Process) provides means for all of this.

I'm afraid that we'd need a bit more information on what is your
situation and what you try to achieve. In particular:
1) What kind of an application is your program (console, GUI, ...),
under which operating system?
2) You mention that there is another program that is still running -
do
you mean that the remaining program starts the crashing one and you
would like to check the results? If this is the case, how you start
the
program (Dos.Exec, SysUtils.ExecuteProcess, Process.TProcess, ...)?
3) What do you mean if you say "crashes" - a run-time error? Or a GUI
message box stating that the program crashed? Or...?
