[Mimedefang] MIMEDefang 2.60 + sendmail 8.14.0 abort with signal 11

[curioso]

I recently update to MD 2.60 and sendmail 8.14.00

When I send -or receive- a message with a written accent vowels
-tilde- (áéíóú) in subject, mimedefang die with signal 11 (perhaps
kernel trap some extrange MD action)

I add to sendmail.mc    define(`confMILTER_LOG_LEVEL', `99')   and
here are the logs:
