Yes, vi.
vi innshellvars
/SED
*boom* sig11.
Sed is failing during the run of $inn/innshellvars (from
inn1.4unoff2). I've recompiled sed with "-g" and here it goes. I was
editing inndshellvars to replace /usr/bin/sed by ./sed with a "/SED" when
"vi" sig11'ed.

Is the "Address XXXXXX out of bounds" expected or not ?
