The bug is caused by using already freed memory. If there is already an attempt and execute 'reconnect -r' command, all the ConfigFormEntry structure will be freed in IScsiDriverBindingStop, but the mCallbackInfo->Current is not configured as null and this pointer will be used again in IScsiFormExtractConfig.
