In-house use is normally not in violation of the GPL.
In your example, as long as your program is never sold or distributed in
binary form (ie. you did not sell or give it to the bank in binary
form because the bank owned your labor that created it), and the bank
never sells or distributes the binaries outside itself, I think you are
ok.
Since these types of distinctions look legally cloudy to me, I would
hesitate strongly to agree with your "goes by the wayside for all
non-software development companies" statement.
That said, you should consult a lawyer. No one on this list is
a qualified GPL authority. Only the courts can make a determination.
CGF, the closest person here to an authority, hates GPL conversations.
Don't expect him to speak up unless you are clearly in violation, or this
conversation has already (as it probably has) gone on too long.
