OK, this was the bit of info I was missing. I put a call in
SubPostmasterMain() like this:
_setmode(fileno(stderr), _O_BINARY);
and one in the syslogger code the same, just after the pipe is dup'ed
into stderr.
After that I saw no more corruption issues.
However, the problem is that in backporting it we'd make a slight
behaviour change - the log file just gets LF instead of CRLF line
endings. I'm inclined to say that's a better result than living with the
bug, though.
Thoughts?
