enabling debugging

Hi, I am getting segfaults/bus errors when using APC. I am using APC-2.0.4 compiled as a DSO to cache Horde/IMP. %> /usr/local/bin/phpize %> ./configure --enable-apc --with-gnu-ld I am also using a daily snapshot of PHP (php4-STABLE-2005011819) because the current stable 4.3.10 gives compilation errors with my options: ./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-gettext --with-xml --with-dom --with-pgsql --with-mcrypt --with-iconv --enable-mbstring --with-mbstring=all --with-zlib-dir=/usr/include --with-imap --with-openssl --with-ldap --with-kerberos --with-imap-ssl Debian Sarge with 2.6.8-smp kernel on an UltraSPARC e450 box with 2 processors. gcc version 3.3.5 (Debian 1:3.3.5-5) I am not sure how to enable debugging for APC. If I enable debugging in PHP but not APC, PHP can't load APC and I get no segfaults. I also tried compiling APC statically per the INSTALL instructions, but I don't think it's getting used. The app is slow and nothing shows up under phpinfo(). Thanks for any pointers. Arshavir
