We've got a custom milter that uses smfi_getsymval(ctx, "_") to recover
the ident information. This has been working perfectly for many months but
has decided to segfault on a regular basis over the last week or so.
Server's not changed a bit - it's in production, and and change in
configuration would be flagged to me directly - so I'm led to think that
it's the incoming mail content that's causing the problem. I've noticed
that spammers are starting to use apostrophes in the from: address, and
wondered vaguely whether that's the problem.

I know I've presented very little information here, but has anyone else
had a similar problem? If is matters, we're running 8.13.8 under debian
testing.

Cheers, Steve

Perhaps you could get a core dump, build your milter with debugging
information not stripped out and add some syslog debugging of the code
action related to your libmilter call.

Can you show source?
