# Description of the problem I am trying to compile a couple of different software packages. While almost all of my compiles work, two of them, one in a php module and one in a perl module, result in a segfault. # Compiler command and error output Initiated by `pecl install channel://pecl.php.net/svn-0.5.0' gcc -I/usr/include/subversion-1 -I/usr/include/apr-1.0 -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE -D_LARGEFILE64_SOURCE -I. -I/tmp/pear/temp/svn -DPHP_ATOM_INC -I/var/tmp/pear-build-root/svn-0.5.0/include -I/var/tmp/pear-build-root/svn-0.5.0/main -I/tmp/pear/temp/svn -I/usr/include/php5 -I/usr/include/php5/main -I/usr/include/php5/TSRM -I/usr/include/php5/Zend -I/usr/include/php5/ext -I/usr/include/php5/ext/date/lib -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/subversion-1 -I/usr/include/apr-1.0 -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE -D_LARGEFILE64_SOURCE -DHAVE_CONFIG_H -g -O2 -c /tmp/pear/temp/svn/svn.c -fPIC -DPIC -o .libs/svn.o as: Symbol `i386_regtab' has different size in shared object, consider re-linking as: Symbol `i386_optab' has different size in shared object, consider re-linking gcc: Internal error: Segmentation fault (program as) # Initiated by `cpan install Want' libtool: compile: gcc -I/usr/include/subversion-1 -I/usr/include/apr-1.0 -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE -D_LARGEFILE64_SOURCE -I. -I/tmp/pear/temp/svn -DPHP_ATOM_INC -I/var/tmp/pear-build-root/svn-0.5.0/include -I/var/tmp/pear-build-root/svn-0.5.0/main -I/tmp/pear/temp/svn -I/usr/include/php5 -I/usr/include/php5/main -I/usr/include/php5/TSRM -I/usr/include/php5/Zend -I/usr/include/php5/ext -I/usr/include/php5/ext/date/lib -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/subversion-1 -I/usr/include/apr-1.0 -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE -D_LARGEFILE64_SOURCE -DHAVE_CONFIG_H -g -O2 -c /tmp/pear/temp/svn/svn.c -fPIC -DPIC -o .libs/svn.o as: Symbol `i386_regtab' has different size in shared object, consider re-linking as: Symbol `i386_optab' has different size in shared object, consider re-linking gcc: Internal error: Segmentation fault (program as) # Details about my system :~# gcc --version gcc (GCC) 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2) :~# uname -a Linux grey 2.6.27-7-generic #1 SMP Tue Nov 4 19:33:20 UTC 2008 i686 GNU/Linux :~# cat /etc/lsb-release DISTRIB_CODENAME=intrepid DISTRIB_DESCRIPTION="Ubuntu 8.10" # `env' PATH=./:/root/sbin:/root/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/sbin:/usr/sbin HOSTTYPE=i486-linux VENDOR=intel OSTYPE=linux MACHTYPE=i486 CPU=LINUXdebug LD_LIBRARY_PATH=/usr/local/lib # configure output for pecl install svn checking for grep that handles long lines and -e... /bin/grep checking for egrep... /bin/grep -E checking for a sed that does not truncate output... /bin/sed checking for gcc... gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ISO C89... none needed checking whether gcc and cc understand -c and -o together... yes checking for system library directory... lib checking if compiler supports -R... no checking if compiler supports -Wl,-rpath,... yes checking build system type... i686-pc-linux-gnu checking host system type... i686-pc-linux-gnu checking target system type... i686-pc-linux-gnu checking for PHP prefix... /usr checking for PHP includes... -I/usr/include/php5 -I/usr/include/php5/main -I/usr/include/php5/TSRM -I/usr/include/php5/Zend -I/usr/include/php5/ext -I/usr/include/php5/ext/date/lib -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 checking for PHP extension directory... /usr/lib/php5/20060613+lfs checking for PHP installed headers prefix... /usr/include/php5 checking for re2c... re2c checking for re2c version... 0.13.3 (ok) checking for gawk... gawk checking for svn support... yes, shared checking for specifying the location of apr for svn... yes, shared checking for svn includes...
