    What kind of problems?

    The zshrc and .zshrc files are read for ALL interactive shells,
no matter if they are login shells or not. If you want to do things
only for login shells, do them in zprofile and .zprofile files (and
zlogin and .zlogin, of course).

> How does zsh differentiates between them

    Do you mean between a login shell and a not login shell? Well, if
zsh is invoked as "/bin/zsh -l" then it is a login shell, and if the
first character of the invocation name is '-' (for example, the
/bin/login program exec()'s the shell as -/bin/zsh).

    They don't interact except if some environment variable affects
the behaviour of gdb, or maybe some tty setting. zsh will fork&exec
gdb, which in turn forks+exec+ptraces the debugged program (AFAIK).

    Please, tell us (or better, since this doesn't seem to be
zsh-related, just tell *me* in private) which kind of problem do you
have when debugging programs and we look after a solution ;)
