AxKit Segfaults
Hi all, I was excited about AxKit. :( I'm getting segfaults on the first request, but have neither expat (strings shows now symbols in httpd, mod_perl built with DO_HTTPD=1), nor php installed. Any other ideas? I'm building with debug flags now. apache-1.3.22 mod_perl-1.26 perl-5.6.1 Thanks, Aaron -- aaron ross . alias i, inc email . [EMAIL PROTECTED] phone . 215 545 6428
