Does it occurr in gzdoom 323? If yes, does it also in latest zdoom svn?

No. In GZDoom 323, the player only picks up the megasphere when s/he starts to move, or crouches.

bool G_CheckSpotNoPickup (int playernum, FMapThing *mthing)
{
  const bool hadPickup = ( players[playernum].mo && players[playernum].mo->flags & MF_PICKUP );
  // [TP/BB] Prevent the current player body from picking up anything with the G_CheckSpot call.
  if ( hadPickup )
    players[playernum].mo->flags &= ~MF_PICKUP;
  const bool ret = G_CheckSpot (playernum, mthing);
  // [BB] Restore the flag if necessary.
  if ( hadPickup )
    players[playernum].mo->flags |= MF_PICKUP;
  return ret;
}
