Hi, I need some help in migrating our existing code from RHEL4 to centOS 4.2. We use apache configured as a proxy server and ,we have an out filter module registered with apache 2.2.4, where we gets the page content and do some processing based on the content. Everything worked fine in RHEL4 but when the same code was migrated to CentOS4.2 and compiled there ,a segmentation fault occurs while loading the module. we have some infilter modules also registered but did not face any problem with loading them, the issue is with the loading the out filter.
details of the setup apache was configured with following command ./configure --prefix=/usr/local/apache2 --enable-mods-shared="proxy_connect proxy_ftp proxy_http proxy status rewrite deflate" --with-mpm=worker --with-included-apr uname -a : Linux srv-ind-ffi12.vanenburg.com 2.6.9-22.ELsmp #1 SMP Sat Oct 8 19:11:43 CDT 2005 i686 i686 i386 GNU/Linux gcc version: Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-java-awt=gtk --host=i386-redhat-linux Thread model: posix gcc version 3.4.4 20050721 (Red Hat 3.4.4-2) The following is the back trace using gdb.
