Subject Re: Segfault in ap_vformatter on httpd startup
Date Mon, 26 Aug 2002 22:04:28 GMT

I have done just enough looking at this problem to be thoroughly 
confused.  Basically, if I run test/teststr, I get the seg fault, but if
I run test/.libs/teststr, everything just works.  I have re-built
multiple times, so I am at a complete loss here.  I'll try to look at this
later tonight when I get home.
