Yeah, that seems like a bug. I think the reason is that syslogger.c does this when writing the log metafile: fh = fopen(LOG_METAINFO_DATAFILE_TMP, "w"); ... #ifdef WIN32 /* use CRLF line endings on Windows */ _setmode(_fileno(fh), _O_TEXT); #endif while misc.c only does this when reading the file: fd = AllocateFile(LOG_METAINFO_DATAFILE, "r"); Somehow, the reading file is being left in binary mode and thus it's failing to convert \r\n back to plain \n. Now the weird thing about that is I'd have expected "r" and "w" modes to imply Windows text mode already, so that I'd have figured that _setmode call to be a useless no-op. Apparently on some Windows libc implementations, it's not. How was your installation built exactly? regards, tom lane
