在src\recvdlg.cpp文件里，函數BOOL TRcvDlg::RecvDirFile(void)中存在一個bug，該bug導致自動接收時，接收文件體積大小的門限值乘積產生溢出，不對過大的文件進行接收；需要做如下修改：

BOOL TRecvDlg::RecvDirFile(void) { #define PEEK_SIZE 8if (fileObj->status == FS_DIRFILESTART || fileObj->status == FS_TRANSINFO) {int size;if (fileObj->infoLen == 0) {if ((size = ::recv(fileObj->conInfo->sd, fileObj->info + (int)fileObj->offset,PEEK_SIZE - (int)fileObj->offset, 0)) <= 0) {return FALSE;}if (fileObj->aes.IsKeySet()) {fileObj->aes.DecryptCTR((const BYTE *)fileObj->info + (int)fileObj->offset,(BYTE *)fileObj->info + (int)fileObj->offset, size);}if ((fileObj->offset += size) < PEEK_SIZE) {return TRUE;}fileObj->info[fileObj->offset] = 0;fileObj->infoLen = strtoul(fileObj->info, 0, 16);if (fileObj->infoLen >= sizeof(fileObj->info) -1 || fileObj->infoLen <= 0) {return FALSE; // too big or small}}if (fileObj->offset < fileObj->infoLen) {if ((size = ::recv(fileObj->conInfo->sd, fileObj->info + (int)fileObj->offset,fileObj->infoLen - (int)fileObj->offset, 0)) <= 0) {return FALSE;}if (fileObj->aes.IsKeySet()) {fileObj->aes.DecryptCTR((const BYTE *)fileObj->info + (int)fileObj->offset,(BYTE *)fileObj->info + (int)fileObj->offset, size);}fileObj->offset += size;}if (fileObj->offset == fileObj->infoLen) {fileObj->info[fileObj->infoLen] = 0;if (!DecodeDirEntry(fileObj->info, &fileObj->curFileInfo, fileObj->isDir ? fileObj->u8fname : NULL)) {return FALSE; // Illegal entry}if (isAutoSave) {if (fileObj->totalTrans + fileObj->curFileInfo.Size() >(int64)cfg->autoSaveMax * 1000 * 1000) return FALSE; // 添加(int64)}fileObj->offset = fileObj->infoLen = 0; // 初期化DWORD attr = fileObj->curFileInfo.Attr();if (GET_MODE(attr) == IPMSG_FILE_DIR) {char buf[MAX_BUF];const char *fname = (fileObj->dirCnt == 0) ?fileObj->fileInfo->Fname() : fileObj->curFileInfo.Fname();if (!fileObj->isDir) return FALSE;if (MakePath(buf, fileObj->path, fname) >= MAX_PATH_U8) {MessageBoxU8(buf, GetLoadStrU8(IDS_PATHTOOLONG));return FALSE;}if (!IsSafePath(buf, fname)) {return FALSE;}if (!CreateDirectoryU8(buf, NULL)) {return FALSE;}strncpyz(fileObj->path, buf, MAX_PATH_U8);fileObj->dirCnt++;}else if (GET_MODE(attr) == IPMSG_FILE_RETPARENT) {if (!fileObj->isDir) return FALSE;if (fileObj->curFileInfo.Mtime()) { // directory の time stamp をあわせる(NT系のみ)FILETIME ft;HANDLE hFile;UnixTime2FileTime(fileObj->curFileInfo.Mtime(), &ft);if ((hFile = CreateFileU8(fileObj->path, GENERIC_WRITE, FILE_SHARE_READ, 0,OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, 0)) != INVALID_HANDLE_VALUE) {::SetFileTime(hFile, NULL, NULL, &ft);::CloseHandle(hFile);}}if (fileObj->curFileInfo.Attr() & IPMSG_FILE_RONLYOPT) {SetFileAttributesU8(fileObj->path, FILE_ATTRIBUTE_READONLY);}if (--fileObj->dirCnt <= 0) {fileObj->status = FS_COMPLETE;return TRUE;}if (!GetParentDirU8(fileObj->path, fileObj->path)) {return FALSE;}}else {if (fileObj->isDir && fileObj->dirCnt == 0) {return FALSE;}if (fileObj->curFileInfo.Size() == 0) { // 0byte fileif (OpenRecvFile()) { // 0byteの場合は作成失敗を無視CloseRecvFile(TRUE);}if (!fileObj->isDir) {fileObj->status = FS_COMPLETE;return TRUE;}}fileObj->status = fileObj->curFileInfo.Size() ?
