Can you send me your patch with the memmove()'s and I'll have a look at it? > Package: tinysnmp-agent > Version: 0.8.4 > Severity: grave > Justification: renders package unusable > > This is the same as #282260, but as that's already archived, I'm opening > a new bug. > > The tinysnmpd daemon still doesn't start on sparc but gives a SIGBUS > instead.
