Subject Re: Huh? Windows oddness (long dbxtrace)
Date Fri, 12 Sep 1997 23:12:43 GMT
I wonder if these are all related to the SEGVs that I started seeing when
I did a "cvs update" after I got back from burning man (tuesday sept 2).
Can you folks try doing a few 'cvs -D "a week ago"' checkouts and see
when it started happening?

I think core_dir->opts is buried under a macro or function call.
