recently i put it inot a two lamp fixture. after the light switch had
been turned off a long time, i reentered the room, and noticed this
bulb was infrequently flashing, as if some kind fo charge was
building then discharging.

possible complicatoins.
3 way (2 locatoin) switch, this switch has the neon(?) indicator in
the switch. ..

That neon indicator on the switch is using the light as part of it's
circuit and that is the source of the power. Slight differences in
designs will cause some CFs to flicker and others not. Put another switch
without as indicator and the problem will go away.

I don't know if this could be a problem for the CF or not.

There's likely no damage being done to the lamp. The current is a few mA --
not enough to seriously cause the cathodes of the CFL lamp to sputter.
That would shorten lamp life. Any other harmful damage would have to
involve heat or voltages beyond the standard line voltage.
