Reply-Path: We have suddenly started to see a problem with /bin/mail in Ultrix 2.0. All mail sent to me from a certain redistribution list (urusei-yatsura@panda.com -- I just joined it the other day) causes /bin/mail to do the following: - Receive the mail from sendmail. The "From:" line is quite long, usually about 110 characters, but the buffer used by /bin/mail has plenty of room for this. - Deliver the mail to my spool file, no problems so far. - Receive a SIGILL -- who knows why? Difficult to debug too. - Go to the signal catcher, which cleans up and does a longjmp() back to main(). - Hang inside the longjmp, forever using all it can get of the CPU. We have the source and I expect to be able to locate and fix this myself, so this is really a warning, not a plea for help. Has everyone seen a problem like this with /bin/mail? I think it may be ULTRIX-specific because DEC made changes to /bin/mail for locking files in the presence of NFS recently. The funny thing is that I can't get it to behave badly for any mail message not sent from urusei-yatsura. -D.
